stringSize: Size of a character string in current font

In ifultools: Insightful Research Tools

Description

Calculates the approximate relative x and y spans of the input character string x in the current par("usr") coordinates. The srt, adj, and cex inputs are exactly those specified by the par function.

Usage

stringSize(x, srt=0, adj=0.5, cex=1)

Arguments

x	a character string.
adj	a numeric value on the interval [0,1] used to justify the text relative to its placement in a plot. Default: 0.5 (center aligned).
cex	the expansion value for the character string. Default: 1.
srt	a numeric value defining the amount of string rotation in degrees. Default: 0.

Value

a list of x- and y-vectors that can be used to estimate the width and height, respectively, of the input character string in the current par("usr") coordinates. Each vector contains a relative starting and ending value and the absolute difference between the two values repesents the span in the corresponding direction.
