I just want to integrate a 3D data set along one dimension to obtain a
2D data set. Something like:
(given array "d" with dim nx,ny,nz ...)
data_int<-array(dim=c(nx,ny))
for (n in 1:ny) {
for (m in 1:nx) {
data_int[m,n]<-sum(d[m,n,])
}
}
The thing is, given R's facility with integers, it seems that I should
be able to obtain data_int without the explicit for-loops, but I haven't
been able to figure out how to do it. Anyone know how? Thanks.
