Re: [R] Words near one another.

Problem is not that your question is obvious, but that it is not clear what you want. However, you should be aware that R is a powerful programing language in which almost any algorithm you can find can be implemented. If you don't find answers when you Google or read the Text analysis Task Vi

[R] RExcel issues

Hi - For a while I've used RExcel without problems to run a repeating portfolio optimization problem where I solve for a portfolio allocation targeting a particular risk, then solve for a different risk, etc. I call the commands with (e.g.) rinterface.Rrun "(R command)" Recently that macro sta

Good question Rolf. Rui, thanks for pointing out dyn.unload. When I started using Rcpp a couple of years ago I got burned by stale .so enough times that I adopted a policy of recompile-then-start new R session. My workflow does not include Rolf's "brazillion" repeats, so the overhead of this approa

Re: [R] how to make row.names based on column1 with duplicated values

You can do this with ave(): gene <- c("a","b","c","d","c","d","c","f") ave(gene, gene, FUN=function(x)if(length(x)>1)paste(x,seq_along(x),sep="-") else x) # [1] "a" "b" "c-1" "d-1" "c-2" "d-2" "c-3" "f" You can probably speed it up a bit by pulling the paste() out of FUN and doing it later.

Re: [R] Repeated use of dyn.load().

Hello, In such cases, with C code, I call dyn.unload before loading the modified shared lib again. I don't know if this changed recently, but it used to be needed or else R wouldn't load the new lib. When I call dyn.unload followed by dyn.load I never had problems. (Or the other way around, c

Hi You probably meant make.unique( gene, sep="-" ) [1] "a" "b" "c" "d" "c-1" "d-1" "c-2" "f" I second your objection to such name tweeking. Cheers Petr > -Original Message- > From: R-help [mailto:r-help-boun...@r-project.org] On Behalf Of Jeff > Newmiller > Sent: Thursday, March

[R] Repeated use of dyn.load().

I am working with a function "foo" that explicitly dynamically loads a shared object library or "DLL", doing something like dyn.load("bar.so"). This is a debugging exercise so I make changes to the underlying Fortran code (yes, I acknowledge that I am a dinosaur) remake the DLL "bar.so" and
