Yup, there's a bug in there somewhere, MatrixAssign ends up getting
called with the symbol "value" where the actual replacement value
should have been.
Of course, the whole point becomes a bit moot when one considers
*removing* rows and columns from a matrix...
To tickle the bug:
"[<-.zoffset" <- function(x, i, j, value)
{
if(!missing(i) && is.numeric(i)) i <- i+1
if(!missing(j) && is.numeric(j)) j <- j+1
NextMethod("[<-")
}
m<-matrix(1:4,2,2)
m[0,]<-4:5
Probably, set a breakpoint in do_subassigne and step through it.
