Failed with error: ‘package ‘sentiment’ was built before R 3.0.0: please re-install it’

Question

I am trying to run the snaMIC.R script which is doing sentiment analysis on twitter data. But it is failing with an error saying package sentiment was built before R 3.0.0: please re-install. I am using R-3.1.0 i386 (32 bits win). Another thing that I noted is that I am not getting the sentiment package under "Install packages". I downloaded sentiment_0.2.zip file from http://cms.unipune.ernet.in/~webmaster/cran/bin/windows/contrib/2.14/sentiment_0.2.zip and unpacked it successfully under the default R win-library. But the sentiment package is still not available under "Install packages". I added some more repositories but that did not help. Any suggestions will be highly appreciated.

Answer 1

First, I notice that URL actually offers to download RStem.zip, not sentiment_0.2.zip.

I think what your error message would be more helpful saying is: you've downloaded a binary package for R 2.14, go and find the binary package for R 3.0 (or later) and download and install that instead.

Here are the 3.1 packages: http://www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/3.1/

So perhaps you can try downloading and installing: http://www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/3.1/Rstem_0.4-1.zip

If that doesn't work, you could try finding the source package and installing it that way. But on Windows that might be non-trivial...

Answer 2

I have come over the solution for above problem of "Failed with error: 'package 'sentiment' was built before R 3.0.0: please re-install it". Used the following sequence of commands from R console:

require(devtools)
install_url("http://cran.r-project.org/src/contrib/Archive/sentiment/sentiment_0.2.tar.gz")
require(sentiment)
ls("package:sentiment")
