hi,
I have been trying to do this in R (have implemented it in Excel) but I have
been using a very inefficent way (loops etc.). I have matrix A (columns are
years and ages are rows) and matrix B (columns are birth yrs and rows are
ages)
I would like to first turn matrix A into matrix B
And then I would like to convert matrix B back again to the original matrix
A. (I have left out details of steps) but this is the gist of what I want to
do. Can anyone please give any insights?
Thanks
