I would personally use grid for this. library(grid) grid.rect(width = 5, height = 3, default.units = "cm")

2008/10/16 Thomas Steiner <[EMAIL PROTECTED]>:Hi I want to draw sth in a pdf file with a predefined defined size. Say a 5cm x 3cm rectangle (a ruler): pdf("rect.pdf", paper="a4") plot(c(1,5,5,1,1),c(1,1,3,3,1),asp=1,axes="n") dev.off() but how do I fix that one unit is 1cm?I just did help.search("inch") and found xinch: 'xinch' and 'yinch' convert the specified number of inches given as their arguments into the correct units for plotting with graphics functions. Usually, this only makes sense when normal coordinates are used, i.e., _no_ 'log' scale (see the 'log' argument to 'par'). Then help.search("cm") gave me cm: Description: Translates from inches to cm (centimeters). You just need the inverse of this. Not too hard. Also, the symbol() function takes an inches=TRUE parameter that lets you specify inches as the object size. The grid graphics package has a units system as well, but I've not played with that. See help("unit") for info.
