i wish to know how to set a folder in computer as a mirror from which i can
install packages
i am aware of the menu approach- "Packages>install from local zip files" but
i wish to know the command line approach because i dont have internet access
on the computer where i will be using R.
i have put the zip files of packages in
C:\R\packages\bin\windows\contrib\2.11
i have put the following lines in Rprofile.site
local({r <- getOption("repos")
r["CRAN"] <- "file://C:/R/packages/"
options(repos=r)})
but when i run install.packages("package_name_here"), i get the following
message:
Warning in gzfile(file, "r") :
cannot open compressed file
'//C:/R/packages/bin/windows/contrib/2.11/PACKAGES', probable reason 'No
such file or directory'
Error in gzfile(file, "r") : cannot open the connection
Please help
