DescTools (version 0.99.43)

Stamp: Date/Time/Directory Stamp the Current Plot

Description

Stamp the current plot in the extreme lower right corner. A free text or expression can be defined as text to the stamp.

Usage

Stamp(txt = NULL, las = par("las"), cex = 0.6)

Arguments

txt

an optional single text string. If it is not given, the function will look for a defined option named stamp. If not found the current date will be taken as text. If the stamp option is defined as expression the function will evaluate it. This can be used to define dynamic texts.

las

numeric in 1,3, defining direction of the text. 1 means horizontal, 3 vertical. Default is taken from par("las").

cex

numeric character expansion factor; multiplied by par("cex") yields the final character size. Defaults to 0.6.

Details

The text can be freely defined as option. If user and date should be included by default, the following option using an expression will help:

DescToolsOptions(stamp=expression(gettextf('%s/%s',
          Sys.getenv('USERNAME'), Format(Today(), fmt='yyyy-mm-dd') )))

For R results may not be satisfactory if par(mfrow=) is in effect.
