无法安装Quantreg软件包并更新R版本

Question

I am using R version 3.3.1 on RStudio interface, and a Windows 10 OS. I was trying to install the 'quantreg' package for quantile regression, however I was getting the error message

Warning in install.packages : InternetOpenUrl failed: 'The operation timed out'

Warning in install.packages : downloaded length 180224 != reported length 1521162

Warning in install.packages : package 'quantreg' is not available (for R version 3.3.1)

I repeated the process afterwards several times but got the last line of the above error all the time. Thinking it was due to using an older R version, I tried updating by installing the 'installr' package, but that too gave me the same error as above. I tried updating R from the Tools Menu, but it kept telling me that the current R version is the latest. Also this is my first time here, so apologies if I've messed up the blockquoting.

Answer 1

You need to downgrade R.

Download an older version here (I recommend 3.2.5) and install.

Then (in R), go to Tools > Global Options > press the "Change" button.

Now simply select the version you want and restart R and try reinstalling the package.
