matplot(t, pch = 1:4, type = o, col =

then custozie by yourself ayour axes

Try suppresing the axes with plot(...,xaxt='n')
and adding a custom axis with the command
axis(1,labels=LETTERS[1:5],at=1:5)
see ?axis for more info

Some additional details would help. What platform? What does the C++ code do
that might cause a memory leak? How are you calling it?
I don't see why unloading the library would free memory even if it were
allocated outside R's memory management. Unless you're using Windows you
don't need to
