postxt: Computes coordinates defined from their relative position on x and y in the plotting region

Description

Computes coordinates defined from their relative position on x and y in the plotting region

Usage

postxt(cd = "ul")

Arguments

cd

a numerical vector of length 2, values comprised between 0 and 1, or one predefined among "ul", "bl", "ur", "br", "uc", "bc", "ml", "mc", "mr"

Value

A list:

x

coordinate on x

y

coordinate on y

Details

The argument cd gives the relative position to be computed in ratio of the x or y axis. For instance c(0.025,0.985) means 2.5 percents on the maximum range of the plot region on x, and 98.5 percents on y (means: close to the upper left corner of the plotting region). Predefined positions are available: "ul", upper left,"bl" bottom left, "ur" upper right, "br" bottom right", "uc" upper center, "bc" bottom center", "ml" medium left, "mc" medium center, "mr" medium right
