Hi all, I created environment "mytoolbox" by : mytoolbox <- new.env(parent=baseenv()) Is there anyway I put it in the search path ? If you need some background : In a project, I often write some small functions, and load them into my workspace directly, so when I list the objects with ls(), it looks pretty messy. So I am wondering if it is possible to creat an

Hi, I am writing a function and need to pass a function expression as an argument, for instance, myfun <- function( express) { x<- c(1,2,3) y<-express } if I call the above function by myfun( x*2 ), I get 2 as the result, instead of 2,4,6 , could someone help me to fix this problem ? Furthermore, is that

Hi, I would like to assign a value to a member b of the list a in position 3, by calling: assign( target, 2.34, 3) My question is what the "target" should be. I tried target <- paste("a", $, "b") and something else, but haven't got the right answer yet. BTW, if I attached a list named

Did some search but couldn't find useful result. I am trying to read a n*m dimension data with read.table, what i need is a numeric array, is there any efficient way to allow me get this array directly instead of a list? I tried to use as.array() to change the mode, but seems it doesn't work and i got this error message: "Error in "dimnames<-.data.frame"(`*tmp*`,

Hi All, I have been struggling to figure out how to compile c codes for R use. I am using Win XP + Cygwin + R binaries. After I followed all the instructions in " Building R for Windows" from Murdoch's website, I tried to Run something like : R CMD SHLIB C:\R\test.c , but still didn't get any output. My first question is, does this mean I already did

Hi all, I met a problem while using the debug package, I have the following program: mainfun<- function(){ beta<-1 result<-subfun(beta+x) } subfun<-function(expr){ y <- eval(expr, envir=list(x=c(1,2)),enclos = parent.frame()) return(y) } I have no problem using this program without calling the debug

Hi, I just realized that in Matlab, as long as memory is pre-allocated, doing for-loop doesn't cost more time than doing things in vector form. But it seems in R, it still cost a lot to do for-loop. Is there any improvement in R that I missed. Thanks a lot. Merry Xmas Everyone !

Hello all, I see that R 3.0.0 is announced (hurray!), and have a question regarding this line in the NEWS file: "Packages need to be (re-)installed under this version (3.0.0) of R." Assuming I copy my packages to the new library folder and run "update.packages" will it be enough? Or is there anything more to do? for example - for packages that I have which are already of the

I'm running Debian Squeeze on an amd64 machine and currently have R 2.15.3. Some packages have been installed with aptitude and some with install.packages().

Hello everyone. Currently I am running R 2.2.1 (windows), and I will like to update to 2.3. I wanted to ask if it is possible to update without having to removed 2.2.1; or do I first need to delete 2.2.1? Thank you very much. Tony [[alternative HTML version deleted]]

Dear List, I am currently running R-2.10.1. I wish to install R-2.13.0 or update my R-2.10.1 to the R-2.13.0. I have downloaded R-2.13.0 but wish to seek your advice before installing that.

Hello, The R version on my system is R version 2.8.1 (2008-12-22). I have previously installed all the desired packages for my work - and they have been working fine.

Some of the error messages indicate

Hi Ivan and R - Help Team, Thank you for your prompt response and the helpful information. I have another query: Is there a way to patch or upgrade the existing installation to version 4.4.0, rather than having to uninstall the older version and then install the latest one? A direct upgrade or patch would greatly simplify the process and reduce downtime. Your guidance on this matter would be
