my.function to be called 3*4 times, each time being passed 2 matrices x and y with dim(x)=c(5,6) and dim(y)=c(7,8).
Anyway, thanks for the tip, Andy. Carlos

Off the top of my head, seems like you can abind() the two together and then run apply. See the abind package on CRAN.

Dear R users,
Suppose two arrays which partly have the same dimensions. For instance, a1 and a2 with dim(a1) is c(3,4,5,6) and dim(a2) is c(3,4,7,8). How can I perform an apply on the equivalent part of the dimensions on both arrays simultaneously? Something like:
apply(list(a1, a2), c(1,2), function(x,y) {my.function(x,y)})
A useful bonus would be, assuming that my.function always returns an array withthe same dimensions (e.g., c(2,3,4), that the final result would be an array wit
h dimensions c(3,4,2,3,4).
With best regards,
Carlos
