How can I set a specific CRAN mirror permanently in R?
I want to set it permanently in my laptop so that when I do install.packages()
, it won't ask me again which mirror to choose.

You can set repos in your .Rprofile to restore your choice every time you start R
Edit: to be more precise:
Add
options(repos=structure(c(CRAN="YOUR FAVORITE MIRROR")))
to your .Rprofile
Alternatively, you check your Rprofile.site (in the directory /your-R-installation/etc/ , eg R-2.14.0/etc). There you see following lines commented out :
# set a CRAN mirror
# local({r <- getOption("repos")
# r["CRAN"] <- "http://my.local.cran"
# options(repos=r)})
So remove the comment marks and change "http://my.local.cran" to the correct website.
