But I don't think this is a nice solution. I found another trick, which is to cancel the install.packages() at the first time by "C-c C-c" and re-enter this command again, then the CRAN mirror site selection windows will be pop-up. However, this solution is also not satisfiable.

You haven't said how your calling install.packages(), but by the
sounds of it your not specifying the mirror to use (mention of
library(tcltk) and the pop-up window appearing).

One option would be to load either of the recommended libraries in
your .Rprofile (or windows equivalent, sorry not familiar with
windows).  Alternatively...

Its not a bug in ESS at all.

The simple solution would be to specify the mirror that you want to use.

First select a mirror that is geographically close to you from

To specify the mirror explicitly when  calling the install.packages()
command by for example...

install.packages("gap", repos="http://cran.uk.r-project.org/",
dependencies=T, clean=T)

The 'smart' option (as you can see from ?install.packages) is to set
repos in your .Rprofile (or  windows equivalent).

Something along the lines of....


As mentioned you should set the URL's to reflect your geographically
local repository.

The above example for setting your repos was gleaned from...
