Dear all I'd wonder why executable's debug information size is bigger than gcc dwarf debug info. When I compiled ARM hello world code with -g option, the arm based assembly and executable files are bigger than gcc results significiantly.(apx. 3x) (source file size was only 3KB) I think that both clang and gcc use same dwarf format ver2 for debugging. But I don't know why the clang executable file size is bigger than gcc executable. Could anyone explain about that?

...inning so maybe creating the a matrix or data frame at the beginning and putting the daily ones in something like that would Make it be faster. But, the proboem with this is I eventually do need a zoo object. I ask this question because at around the 250 mark of the loop, things start to slow down significiantly and I think I remember reading somewhere that doing an rbind of something to itself is not a good idea. Thanks. #======================================================================= =============================================== start<-1 for (filecounter in (1:length(datafilenames)))...

Hello every GNU's, I have a question about mt.plot, on multtest package. I'm wondering how do a plot with test like bonferroni, holm, hochberg,... and also résults of SAM(Significiance Analysis Microarrays) as we can see on several document of Sandrine Dudoit. Thanks a lot and Have a nice day Sandrine --------------------------------------------------------------------------------

Hi, Does anyone have any advice on speeding up R functions (short of re-implementing them in C :-) )? I have a function that applies a wilcoxon test to 12 sets of about a quarter of a million pairs (and takes about 3 hours). I've replaced the inner loop I had originally with a function call via mapply, and also considered different approximations of the wilcoxon, rather than that which is
