Question

I was trying to install RTextTools package for R, but failed. Here is the output from the screen

> >  install.packages("RTextTools")
Warning in install.packages("RTextTools") :
  argument 'lib' is missing: using 'C:\Users\datamining\Documents/R/win-library/2.10'
--- Please select a CRAN mirror for use in this session ---
Warning: unable to access index for repository http://www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/2.10
Warning message:
In getDependencies(pkgs, dependencies, available, lib) :
  package ‘RTextTools’ is not available

What’s the reason for this problem, and how to fix it? Thanks.

Answer 1

There are two distinct, but related, issues:

• You are running version 2.10 of R which is two years old. CRAN supports only the current version with pre-built binaries. You could try installing from source.

• RTextTools, as can be seen on its CRAN page also requires at least R version 2.13.

So in short: you should upgrade.
