Hello,
I just wanted to say that I just stumbled upon the solution by accident!
After your comment on lists I searched for some more information on vectors,
lists and matrices. I read that using double ['s instead of singles drops
the names of the dimensions used.
I then gave
parameterList[aCounter, 3] <<- blaah
instead of
parameterList[[aCounter, 3]] <<- blaah
a quick try and voila!
In hindsight I guess I was just thinking to much in python style where
matrices dont have dimension naming. (python being the language in which I
first learned to program and quite similar to R)
But thanks for your help anyway!
