[R] Matlab end operator

2007-06-27 Thread Markus Loecher
Dear list members, I use both R and Matlab and find that each has its own strengths. Matlab definitely has the edge when it comes to the interactivity of its graphs. In addition I find the little operator end extremely useful in indexing arrays. (as in x(1:end,) ) The notation is MUCH more
