There are a few version of apply() (e.g., lapply(), sapply()). I'm wondering if there is one that does not return anything but just silently apply a function to the list argument.For example, the plot function is applied to each element in 'alist'. It is redundant to return anything from apply. apply(alist,function(x){ plot each element of alist})
Just use a for() loop. If you are plotting things, the performance bottleneck is not going to be in the loop.
Sometimes, we get too anal about avoiding for() loops.
