ftable-matrices

Combining flattened tables.

Description

With the method functions described here, flattened (contingency) tables can be combined into more complex objects, of class "ftable_matrix". For objects of these class format and print methods are provided

Usage

## S3 method for class 'ftable'
cbind(..., deparse.level=1)

## S3 method for class 'ftable'
rbind(..., deparse.level=1)

## S3 method for class 'ftable_matrix'
cbind(..., deparse.level=1)

## S3 method for class 'ftable_matrix'
rbind(..., deparse.level=1)

## S3 method for class 'ftable_matrix'
format(x,quote=TRUE,digits=0,format="f",...)

## S3 method for class 'ftable_matrix'
Write(x,
                            file = "",
                            quote = TRUE,
                            append = FALSE,
                            digits = 0,
                            ...)
                            
## S3 method for class 'ftable_matrix'
print(x,quote=FALSE,...)

Arguments

`...`	for `cbind` and `rbind` methods, two or more objects of class `"ftable"` or `"ftable_matrix"`; for the other methods: further arguments, ignored.
`deparse.level`	ignored, retained for compatibility reasons only.
`x`	an object used to select a method.
`quote`	logical, indicating whether or not strings should be printed with surrounding quotes.
`digits`	numeric or integer, number of significant digits to be shown.
`format`	a format string as in `formatC`
`file`	character string, containing a file path.
`append`	logical, should the output appended to the file?

Value

cbind and rbind, when used with "ftable" or "ftable_matrix" objects, return objects of class "ftable_matrix".

Examples

ft1 <- ftable(Sex~Survived,Titanic)
ft2 <- ftable(Age+Class~Survived,Titanic)
ft3 <- ftable(Survived~Class,Titanic)
ft4 <- ftable(Survived~Age,Titanic)
ft5 <- ftable(Survived~Sex,Titanic)

tab10 <- xtabs(Freq~Survived,Titanic)

(c12.10 <- cbind(ft1,ft2,Total=tab10))
(r345.10 <- rbind(ft3,ft4,ft5,Total=tab10))

## Not run: 
tf <- tempfile()
Write(c12.10,file=tf)
file.show(tf)

## End(Not run)
