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.
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.
