Am I being too optimistic in expecting this (mixing and matching
matrices and Matrices) to work? If x is a matrix and m is a Matrix,
replacing a commensurately sized sub-matrix of x with m throws "number
of items to replace is not a multiple of replacement length" ...
x <- matrix(0,nrow=3,ncol=10, dimnames=list(letters[1:3],LETTERS[1:10]))
rr <- c("a","b","c")
cc <- c("B","C","E")
m <- Matrix(matrix(1:9,3,3))
x[rr,cc] <- m
cheers
