...l is part of the ... argument list which is passed on to localAxis (and from there to axis). Wouldn't it be more approptiate to use the same color box() uses to draw the border around each scatterplot? If yes, should I open a bug for this or how would such a feature request be handled? -- Olaf Mersmann

...to accept > 20x2 [1] 20 as input. This appears to be related to the parsing of hexadecimal constants, since there must be a zero before the 'x' (i.e. 2x2 or 02x02 gives the expected error). All this is under R 2.12.1 on both OS X and Linux. Is this expected behavior? Cheers, Olaf Mersmann

...system wide one, so it might not be worth the trouble of patching the sources instead of waiting for a new release. If anyone wants to apply a fix, I have prepared a patch with all the changes which can be found here http://www.statistik.tu-dortmund.de/~olafm/temp/xz_restrict.patch Cheers, Olaf Mersmann

...but I've been unable to come up with a solution that works with two or more columns. In SQL a query to achieve this would look something like this: SELECT f1, f2, sum(c1), sum(2) FROM df GROUP BY f1, f2 An hints on how this is done efficiently in R would be greatly appreciated. Thanks, Olaf Mersmann

...t;- function(f) { f <- match.fun(f) function(...) !f(...) } This matches 'f' when Negate() is called and not the first time the return value is used. If the current behavior is desired, maybe a note in the documentation could be added to clarify this peculiarity. Cheers, Olaf Mersmann

...fuction entry and return and one which fires before / after a garbage collection. Is there any interest in merging something like this into R-devel? If yes, I'd like to discuss which probes and what data would be useful / interesting from a developers standpoint.

Hi, `model.matrix' might kill R with a segfault (on a illposed problem, but anyway): mydf <- as.data.frame(sapply(1:40, function(i) gl(2, 100))) f <- as.formula(paste("~ - 1 + ", paste(names(mydf), collapse = ":"), sep = "")) X <- model.matrix(f, data = mydf) *** caught segfault *** address 0x18, cause 'memory not mapped' Segmentation fault

Dear List, I have acquired a new desktop and wanted to put a free OS on it. I am trying Fedora Core 1, but not sure what the best Linux OS is for using R 2.0.1?
