Installing Packages from a Local Repository

Hi everyone,

I've followed the instructions from R-Admin Section 6.6 for creating a
local repository. I've modified my Rprofile.site file to add the local
repository to my repos, but I haven't been able to successfully install my
package from the repo.

Here's the code that I've run.

##################################
sessionInfo()
getOption("repos")
setwd("Q:/Integrated Planning/R")
list.files(path = ".", recursive = TRUE)
tools::write_PACKAGES("bin/windows/contrib/2.15", type = "win.binary")
list.files(path = ".", recursive = TRUE)

install.packages("RTIO")
install.packages("RTIO", repos = "Q:/Integrated Planning/R")
install.packages("RTIO", repos = "Q:/Integrated Planning/R", type =
"win.binary")

unlink(c("bin/windows/contrib/2.15/PACKAGES","bin/windows/contrib/2.15/PACKAGES.gz"))
############


And here it is with output included:

I'd really like to be able to use "install.packages("RTIO")" without having
to specify the repo, as this will make it easy for our other less
experienced R users.

Any ideas why I get "warning: cannot open compressed file" and "error:
cannot open the connection"? As far as I can tell, I've followed the
R-Admin 6.6 instructions exactly.

If it matters, Q: is a mapped network drive.
