Subject: applying cbind (or any function) across all components in a list
#If I have two lists as follows
a1<- array(1:6, dim=c(2,3))
a2<- array(7:12, dim=c(2,3))
l1<- list(a1,a2)
a3<- array(1:4, dim=c(2,2))
a4<- array(5:8, dim=c(2,2))
l2<- list(a3,a4)
#how can I create a new list with the mean across all arrays within the
list, so all components are included? As an example for [[1]];
cbind((l1[[1]][,1]+l2[[1]][,1])/2, (l1[[1]][,2]+l2[[1]][,1])/2,
(l1[[1]][,2]+l2[[1]][,2])/2, (l1[[1]][,3]+l2[[1]][,2])/2)
