I don't see any attempt to load the package.  You attempted to use the 
function Simplex and it was not found.  That indicates the package is 
not loaded, but not why.

What you should show are the messages you get when you start a clean 
copy of R and immediately attempt to load the package using library(). 
It's helpful that you posted sessionInfo(); I'd include that again with 
the new information, in case anything is different.
