DescTools Options
Get and set a variety of options which affect the way in which DescTools functions display results.

Invoking DescToolsOptions() with no arguments returns a list with the current values of the options. Note that not all options listed below are set initially. To access the value of a single option, one can simply use DescToolsOptions("plotit").
To set a new value use the same rationale as with the R options: DescToolsOptions(plotit=FALSE)
Options used by DescTools
col:a vector of colours, defined as names or as RGB-longs ("#RRGGBB"). By now three colors are used in several plots as defaults. By default they're set to hblue, hred and horange. Change the values by defining DescToolsOptions(col=c("pink", "blue", "yellow")). Any color definition can be used here.
digits:the number of FIXED digits, used throughout the print functions.
fixedfont:this font will be used by default, when Desc writes
to a Word document. Must be defined as a font object, say enumerating name, face and size of the font and setting the class font, e.g. structure(list(name="Courier New", size=7), class="font").
fmt:Three number format definitions are currently used in the Desc routines. The format used for integer values is named "abs", for percentages "perc" and for floating point numeric values "num".
The format definitions must be of class "fmt" and may contain any argument used in the function Format.
Use Fmt to access and update formats (as they are organised in a nested list).
footnote:a character vector, containing characters to be used as footnote signs.
Any character can be defined here. This is currently used by TOne.
lang:either "engl" or "local", defining the language to be used for the names of weekdays and months when using Format.
plotit:logical, defining whether the Desc-procedures should produce plots by default. This is usually a good thing, but it may clutter up your desktop, if you're not using RStudio. Therefore it can be turned off.
stamp:text or expression to be placed in the right bottom corner of the DescTools plots. This can be useful, if some author or date information should automatically be inserted by default. Any text can be set as option, but also dynamic expressions can be used. The default would use an expression as <username>/<date>, which will use the username from the system and the current date. See defaults below.
Calling DescToolsOptions(reset=TRUE) will reset the options to these defaults:
options(DescTools = list(
col = c(hblue="#8296C4", hred="#9A0941", horange="#F08100"),
digits = 3,
fixedfont = structure(list(name = "Consolas", size = 7), class = "font"),
fmt = list(abs = structure(list(digits = 0, big.mark = "'"),
name = "abs", label = "Number format for counts", default = TRUE,
class = "fmt"),
per = structure(list(digits = 1, fmt = "%"),
name = "per", label = "Percentage number format", default = TRUE,
class = "fmt"),
num = structure(list(digits = 3, big.mark = "'"),
name = "num", label = "Number format for floats", default = TRUE,
class = "fmt")
),
footnote = c("'", "\"", "\"\""),
lang = "engl",
plotit = TRUE,
stamp = expression(gettextf("%s/%s", Sys.getenv("USERNAME"),
Format(Today(), fmt = "yyyy-mm-dd")))
))This code can as well be copied and pasted to the users' RProfile file, in order to have the options permanently available.
For a given vector of strings the current value set for option x, or NULL if the option is unset.
If called with no arguments, returns all option settings in a list. Otherwise, it changes the named settings and invisibly returns their previous values.
