...it seems somewhat inelegant. paste.vector <- function(x, ...) { output <- NULL for (i in 1:length(x)) output <- paste(output, x[i], ...) output } #end of function definition paste.vector(x) [1] " Bob loves Sally" Is there a more natural (no loop) way to do this in R?

I'm also curious why the following does not work, because it seems to me it should: > test <- function(x) identical(x[1], x[2]) > apply(cbind(x, 5), 1, test) [1] FALSE FALSE FALSE FALSE FALSE I was expecting to see FALSE FALSE FALSE TRUE FALSE.

I''ve just finished installing onto an OCZ Agilent v2 SSD with btrfs as filesystem. However to my surprise I''ve hit an ENOSPC condition one one of the partitions within less than a day of uptime, while the filesystem on that partition only reported 50% to be in use, which is far from the 75% limit people mention on the ML. Note that this occurs using a vanilla 2.6.32-rc5 kernel

To follow up on my previous question, suppose a user R session wants to unload one workspace and load another within an R session. Is the following the correct sequence? 1. save.image() to save the current workspace as .Rdata in the current working directory. 2. rm(list=ls()) to remove everything from the workspace. 3. setcwd("xxx") to set the new working directory. 4.

As an alternative to the use of multiple shortcus to gain entry to different R environments on WIndows platforms I would like to suggest the use of two R functions written by my colleague John Miyamoto. I have taken the liberty of attaching their definitions to this message. Their efficient use is based on adopting the following regimen or something like it: (1) at startup attach an .Rdata workspace containing the two functions, say to position 2. This I do in my etc/Rprofile file. (2) then attac...

Hello R-users, is it possible to navigate from one workspace to the other from within an R session or does one has to close R and restart it from the directory where resides the desired workspace? For example from Splus I have this little function, see at the end, which I used all the time to navigate between valid Splus directories. I find this particularly usefull when I develop new

I have found the use of save( ) and attach( ) when supported by a pair of functions written by my colleague John Miyamoto, move( ) and rm.sv( ) quite useful in managing (1) collections of useful homebrew functions, (2) project workspaces, and (3) "packages" under development. An .Rdata file containing these and other handy functions together with a brief supporting document can be downloaded from a course we...
