cannot install sentiment; Rstem not available about twitter

Yes, I had the same issue; it is because the Rstem package has been removed from CRAN.

I downloaded and installed Rstem from the command-line as follows:

wget  http://www.omegahat.org/Rstem/Rstem_0.4-1.tar.gz
R CMD INSTALL Rstem_0.4-1.tar.gz

Now you should be able to install sentiment from the R console using install.packages().

Reopened only because I should not close without confirmation that my first post fixes the issue :)

Confirmed that your solution works for me.

This is not working anymore

It's not clear from the previous comment what is "not working".

Both Rstem and sentiment were removed from CRAN, but both can still be downloaded and installed. You also need to install the tm package. I just did this successfully on OS X with R 3.3.
