[R] apply in apply

Dear list, I need to apply a function on each column of each matrix contained in a list. Consider the following code, x - 1:3 my.data - list(matrix(c(1,2,3,4,5,6),ncol=2), matrix(c(4,5,6,7,8,9),ncol=2)) par(mfrow=c(2,2)) results - sapply(1:length(my.data), function(ii)

Thank you for the suggestions (off-list as well). I think the best option may eventually be an explicit for loop to make things clearer. To clarify a bit, I've used the plot function in the example where in fact it is a numerical integration (which is why I need to pass an additional
