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.
