Set the r image site in the rprofile. Site File

Set the r image site in the rprofile. Site File

It seems that the official site of R is down, causing errors every time the installation. Packages installation package is installed.

You can set up domestic image sites in the rprofile. Site file.

In Windows, this file is in the c: \ Program Files \ r \ R-2.9.2 \ etc directory (this is my installation location, for reference only)

Modify as follows

# Set a cran mirror
Local ({r <-getoption ("repos ")
R ["cran"] <-"http://cran.csdb.cn /"
Options (repos = r )}
