That means just what it says:  you're trying to install the package into 
a directory, but the administrator of your machine (you?) hasn't given R 
permission to make changes to that directory.  If you are the 
administrator, you might get that to work using "Run as administrator", 
which is an option in Windows when you right click on the R icon.

If you're not the administrator, chances are you'll need to find 
someplace else (where you have write permission) to install that package.

That's because you don't have any object named nnet.  Some functions 
(e.g. library()) guess that you mean "nnet" when you type nnet, but 
install.packages doesn't.  So you should try

  install.packages("nnet")
