Dear Friends, I'm contributing to a paper on a new R package for a clinical (medicine, ophthalmology) audience, and part of the mission is to encourage people who might be occasional users of Excel or SPSS, to become more familiar with R. I'd really appreciate any pointers to more recent papers that describe R, it's growth (statistics on user base, number of packages, volume of help list...

I use R to create .eps graphics and then use oodraw to convert them to .emf versions. (One reason I do this is that OOo tends to re-size .eps files and I haven't found a way to stop it or change it once the graph is resized. .emf files are not distorted by OOo - fortunately.) I use a command like: > oodraw filename.eps & The gui opens and then I select .emf and do an export. I

This is a simple question but I cannot seem to find the answer. I have two vectors but with missing data and I want to add them together with the NA's being ignored. Clearly I need to get the NA ignored. na.action? I have done some searching and cannot get na.action to help. This must be a common enough issue that the answer is staring me in the face but I just don't see it. Simple

The idea is to intercept outbound calls from the Nortel PBX and redirect them via VoIP to another asterisk box at another branch transparently(thus saving the LD cost). Otherwise I'd pass
