This seems very similar to the data.table package. The 'by' argument splits the data.table by that value then executes the j expression within each subset. The package documentation talks about 'subset' and 'with' in some detail. See ?"[.data.table". dt = data.table(x=1:20, y=rep(1:4,each=5)

Dear list, A small follow up on this issue. The same behavior is observed for postscript() and pdf(), so I suspect the erroneous code is in grDevices/src/devPS.c. In particular, this macro, static void PostScriptSetLineTexture(FILE *fp, const char *dashlist, int nlty, double lwd) { /* use same ma

I cannot reproduce this on our x86_64 Fedora systems (and I tried all the usual tricks such as gctorture and valgrind to provoke a problem). And I have fitted much larger GLMs many times over the last decade, so your 'bug summary' cannot be the whole story. Your example is random and you haven'

This is now fixed in R-devel and R-patched as of r50774. It should show up in Windows builds tomorrow. There were probably other special characters besides "?" that it handled incorrectly; thanks for noticing. Duncan Murdoch On 17/12/2009 4:05 AM, henrik.p...@bio.ntnu.no wrote: Dear R deve
