Yes, you should train 5 different models, or find an outcome that can combine them together, since caret only accepts a list or vector as outcome. On Sun, Oct 5, 2014 at 1:51 PM, Lorenzo Isella wrote: > Thanks a lot. > At this point then I wonder: seen that my response consists of 5 > outcomes f

I believe that what is happening is that the clipping region is being reset when you call box, but not when you call rect. If you insert the command "par(xpd=NA)" (or TRUE instead of NA) after the plot.new and use the rect commands then you can see both rectangles (because this turns the clipping
