Im' using matrix() and layout() to set up a fairly complex plot... I was wondering if anyone can point me to something that describes the appropriate incantations to determine, given a text string, the maximum font size that will allow it to fit into the current plotting area without being trunucated?
Well, this depends on the graphics device, and none allows you to choose the font size of a running window. You can use cex, but its mapping to font sizes may well be piecewise constant. So I think the best you can do in general is strwidth/height plus trial-and-error on its cex argument. If you have a specific device in mind, you can find out the cex+ps -> font size mapping byt reading the code or experiment.
