You installed the very latest build of R (3.0.0). The package sentiment is build for R version 2.14.0 and removed in later versions.
Do you work on a Linux Machine? You should be able to install R 2.14.* with the following shell command:
sudo apt-get install r-base-core=2.14.1-1
Maybe you have to install other packages first, like these:
apt-get install r-recommended=2.14.1-1
apt-get install r-base=2.14.1-1
Then you should be able to install the package sentiment.
But maybe you should look for another package in R 3.0.0 that has the same functionality as sentiment...
