Hi, Apologies for using this thread for something that is only tangentially related. Is there a mechanism in R to ensure that the configure.args used to build R is also used when installing packages? If not, I would like to add this as wish (perhaps we can grab this info from config.log?) At the moment, I add the line options(configure.args="...") in my .Rprofile and install.packages() would use them. However, if I change these when building R, I need to remember to change my .Rprofile as well. h.

Dear list members,
The release of R 2.9.0, reminds me of a long-standing nit that I have to
pick. I prefer not to transfer and update all of the packages in my old
library, because I see a new release of R as an opportunity to start with a
clean slate. I'd rather install packages as I need them. My personal
solution is to use the following function in place of library():
package <- function(package, dependencies=TRUE, ...){
package <- as.character(substitute(package))
if (!(package %in% .packages(all.available=TRUE)))
install.packages(package, dependencies=dependencies)
library(package, character.only=TRUE, ...)
}
I'm sure that this function could be improved, and possibly I've missed a
facility that's already available. If not, it would be nice if the library()
command automatically tried to download and install missing packages
(perhaps if an option is set).
Regards,
John
