For latex, any S object. For dvi or dvigv, an object created by latex. For latexTranslate is a vector of character strings to translate. Any NAs are set to blank strings before conversion.

any object to be printed verbatim for latexVerbatim. For latexSN or htmlSN, x is a numeric vector.

name of file to create without the .tex extension. If this option is not set, value/string of x (see above) is printed in the top left corner of the table. Set title='' to suppress this output.

name of the file to create. The default file name is ‘x.tex’ where x is the first word in the name of the argument for x. Set file="" to have the generated LaTeX code just printed to standard output. This is especially useful when running under Sweave in R using its results=tex tag, to save having to manage many small external files. When file="", latex keeps track of LaTeX styles that are called for by creating or modifying an object latexStyles (in .GlobalTemp in R or in frame 0 in S-Plus). latexStyles is a vector containing the base names of all the unique LaTeX styles called for so far in the current session. See the end of the examples section for a way to use this object to good effect. For dvips, file is the name of an output postscript file.

defaults to FALSE. Set to TRUE to append output to an existing file.

a text string representing a symbolic label for the table for referencing in the LaTeX \label and \ref commands. label is only used if caption is given.

If x has row dimnames, rowlabel is a character string containing the column heading for the row dimnames. The default is the name of the argument for x.

If x has row dimnames, specifies the justification for printing them. Possible values are "l", "r", "c". The heading (rowlabel) itself is left justified if rowlabel.just="l", otherwise it is centered.

a vector of character strings defining major column headings. The default is to have none.

a vector containing the number of columns for which each element in cgroup is a heading. For example, specify cgroup=c("Major 1","Major 2"), n.cgroup=c(3,3) if "Major 1" is to span columns 1-3 and "Major 2" is to span columns 4-6. rowlabel does not count in the column numbers. You can omit n.cgroup if all groups have the same number of columns.

a vector of character strings containing headings for row groups. n.rgroup must be present when rgroup is given. The first n.rgroup[1] rows are sectioned off and rgroup[1] is used as a bold heading for them. The usual row dimnames (which must be present if rgroup is) are indented. The next n.rgroup[2] rows are treated likewise, etc.

integer vector giving the number of rows in each grouping. If rgroup is not specified, n.rgroup is just used to divide off blocks of rows by horizontal lines. If rgroup is given but n.rgroup is omitted, n.rgroup will default so that each row group contains the same number of rows.

A character string specifying a LaTeX command to be used to format column group labels. The default, "bfseries", sets the current font to ‘bold’. It is possible to supply a vector of strings so that each column group label is formatted differently. Please note that the first item of the vector is used to format the title (even if a title is not used). Currently the user needs to handle these issue. Multiple effects can be achieved by creating custom LaTeX commands; for example, "\providecommand{\redscshape}{\color{red}\scshape}" creates a LaTeX command called \redscshape that formats the text in red small-caps.

A character string specifying a LaTeX command to be used to format row group labels. The default, "bfseries", sets the current font to ‘bold’. A vector of strings can be supplied to format each row group label differently. Normal recycling applies if the vector is shorter than n.rgroups. See also cgroupTexCmd above regarding multiple effects.

A character string specifying a LaTeX command to be used to format rownames. The default, NULL, applies no command. A vector of different commands can also be supplied. See also cgroupTexCmd above regarding multiple effects.

A character string specifying a LaTeX command to be used to format column labels. The default, NULL, applies no command. It is possible to supply a vector of strings to format each column label differently. If column groups are not used, the first item in the vector will be used to format the title. Please note that if column groups are used the first item of cgroupTexCmd and not colnamesTexCmd is used to format the title. The user needs to allow for these issues when supplying a vector of commands. See also cgroupTexCmd above regarding multiple effects.

A matrix of character strings which are LaTeX commands to be used to format each element, or cell, of the object. The matrix must have the same NROW() and NCOL() as the object. The default, NULL, applies no formats. Empty strings also apply no formats, and one way to start might be to create a matrix of empty strings with matrix(rep("", NROW(x) * NCOL(x)), nrow=NROW(x)) and then selectively change appropriate elements of the matrix. Note that you might need to set numeric.dollar=FALSE (to disable math mode) for some effects to work. See also cgroupTexCmd above regarding multiple effects.

Set to TRUE to use blanks rather than NA for missing values. This usually looks better in latex.

an optional character string to typeset at the bottom of the table. For "ctable" style tables, this is placed in an unmarked footnote.

character string; a tex width controlling the width of the insert.bottom text. Currently only does something with using longtable=TRUE.

a character string to insert as a heading right before beginning tabular environment. Useful for multiple sub-tables.

set to FALSE to use single horizontal rules for styles other than "bookmark" or "ctable"

rownames for tabular environment. Default is rownames of matrix or data.frame. Specify rowname=NULL to suppress the use of row names.

justification for labels for column groups. Defaults to "c".

a character vector of column headings if you don't want to use dimnames(object)[[2]]. Specify colheads=FALSE to suppress column headings.

an optional vector of extra column headings that will appear under the main headings (e.g., sample sizes). This character vector does not need to include an empty space for any rowname in effect, as this will be added automatically. You can also form subheadings by splitting character strings defining the column headings using the usual backslash n newline character.

size for extracolheads or for any second lines in column names; default is "scriptsize"

see format.df

logical, default !dcolumn. Set to TRUE to place dollar signs around numeric values when dcolumn=FALSE. This assures that latex will use minus signs rather than hyphens to indicate negative numbers. Set to FALSE when dcolumn=TRUE, as dcolumn.sty automatically uses minus signs.

logical, set true to place dollar signs around the row names.

set to TRUE to prevent any math mode changes to row names

logical, set true to place dollar signs around the column names.

set to TRUE to prevent any math mode changes to column names

if table.env=TRUE is a character string used to generate a LaTeX hyperref enclosure

a character string used to indicate pages after the first when making a long table

see format.df

Set to TRUE to use David Carlisle's LaTeX longtable style, allowing long tables to be split over multiple pages with headers repeated on each page. The "style" element is set to "longtable". The latex \usepackage must reference [longtable]. The file ‘longtable.sty’ will need to be in a directory in your TEXINPUTS path.

I forgot what this does.

set to TRUE to use Wybo Dekker's ctable style from CTAN. Even though for historical reasons it is not the default, it is generally the preferred method. Thicker but not doubled \hlines are used to start a table when ctable is in effect.

set booktabs=TRUE to use the booktabs style of horizontal rules for better tables. In this case, double \hlines are not used to start a table.

Set table.env=FALSE to suppress enclosing the table in a LaTeX table environment. table.env only applies when longtable=FALSE. You may not specify a caption if table.env=FALSE.

Set to TRUE if you are using table.env=TRUE with longtable=FALSE and you have installed David Carlisle's ‘here.sty’ LaTeX style. This will cause the LaTeX table environment to be set up with option H to guarantee that the table will appear exactly where you think it will in the text. The "style" element is set to "here". The latex \usepackage must reference [here]. The file ‘here.sty’ will need to be in a directory in your TEXINPUTS path. here is largely obsolete with LaTeX2e.

Applies if longtable=TRUE. No more than lines.page lines in the body of a table will be placed on a single page. Page breaks will only occur at rgroup boundaries.

a text string to use as a caption to print at the top of the first page of the table. Default is no caption.

a text string representing a short caption to be used in the “List of Tables”. By default, LaTeX will use caption. If you get inexplicable latex errors, you may need to supply caption.lot to make the errors go away.

set to "bottom" to position a caption below the table instead of the default of "top".

apply the star option for ctables to allow a table to spread over two columns when in twocolumn mode.

set to TRUE to output "\" as "\\" in LaTeX commands. Useful when you are reading the output file back into an S vector for later output.

logical. When vbar==TRUE, columns in the tabular environment are separated with vertical bar characters. When vbar==FALSE, columns are separated with white space. The default, vbar==FALSE, produces tables consistent with the style sheet for the Journal of the American Statistical Association.

justification for column labels.

logical. When TRUE, the default, the name of the function and the assignment arrow are printed to the file.

specifies placement of floats if a table environment is used. Default is "!tbp". To allow tables to appear in the middle of a page of text you might specify where="!htbp" to latex.default.

size of table text if a size change is needed (default is no change). For example you might specify size="small" to use LaTeX font size “small”. For latex.function is a character string that will be appended to "Sinput" such as "small".

default is "center" to enclose the table in a center environment. Use center="centering" or "centerline" to instead use LaTeX centering or centerline directives, or center="none" to use no centering. centerline can be useful when objects besides a tabular are enclosed in a single table environment. This option was implemented by Markus Jäntti markus.jantti@iki.fi of Abo Akademi University.

set to TRUE to enclose the table in a landscape environment. When ctable is TRUE, will use the rotate argument to ctable.

The default uses the S alltt environment for latex.function, Set type="verbatim" to instead use the LaTeX verbatim environment. Use type="Sinput" if using Sweave, especially if you have customized the Sinput environment, for example using the Sweavel style which uses the listings LaTeX package.

width of function text output in columns; see deparse

other arguments are accepted and ignored except that latex passes arguments to format.df (e.g., col.just and other formatting options like dec, rdec, and cdec). For latexVerbatim these arguments are passed to the print function. Ignored for latexTranslate and htmlTranslate. For htmlSN, these arguments are passed to prettyNum or format.

specify additional input and translated strings over the usual defaults

If pb=TRUE, latexTranslate also translates [()] to math mode using \left, \right.

set to TRUE to have latexTranslate put names for greek letters in math mode and add backslashes. For htmlTranslate, translates greek letters to corresponding html characters, ignoring "modes".

single character string to translate NA values to for latexTranslate and htmlTranslate

set to 'unicode' to use HTML unicode characters or '&' to use the ampersand pound number format

set to FALSE to have htmlSN use format instead of prettyNum

horizontal space, e.g., extra left margin for verbatim text. Default is none. Use e.g. hspace="10ex" to add 10 extra spaces to the left of the text.

for S-Plus only; is the length of the output page for printing and capturing verbatim text

are the options( ) to have in effect only for when print is executed. Defaults are current options. For dvi these specify the paper width and height in inches if nomargins=TRUE, with defaults of 5.5 and 7, respectively.

set to TRUE to have dvi print, to the S-Plus session, the LaTeX .log file.

set to FALSE to not use \multicolumn in header of table

set to FALSE to use default LaTeX margins when making the .dvi file
