I just wrote a graphics device taking the X11 device in R-devel as a guide (I was told it's the reference device). It works perfectly with R-devel, but I just noticed that the API (e.g. the use of R_GE_gcontext) is incompatible with previous versions of R. Is the current API in R-devel set in stone or are there any further plans to change the API? (If so, how far?) Also, is there any 'recommended' or 'official' way to provide compatibility (beside using wrappers in various #ifdef's...

Hi! When inserting R plots into a document using odfWeave, I fought for a while to get Lattice plots use the same text size as base plots. I eventually discovered that specifying a point size via e.g. svg(pointsize=10) has no effect on Lattice plots. One needs to adjust the size manually via: trellis.par.set(fontsize=list(text=10, points=8)) This is also developed for both Lattice and ggplot2 by

Grothendieck Version: R version 2.1.0, 2005-05-14 OS: Windows XP Submission from: (NULL) (216.59.254.207) This code: > plot(1:10) > text(5,5,lab=expression(italic(22*"33"))) has the effect of italicizing 33 (which is a character string) but not 22 (which is not). I would have thought that both, not just 33, would be italicized. I had previously posted about this
