Thanks, I've now updated again and this mornings problem is now ok.
But I'm still having trouble with installing the current version of
SparseM. Both of the setMethod calls
setMethod("%*%",signature(x="matrix",y="matrix.csr"),.matmul.matrix.csr)
setMethod("%*%",signature(x="numeric",y="matrix.csr"),.matmul.matrix.csr)
generate errors like this:
Error in setMethod("%*%", signature(x = "matrix", y = "matrix.csr"),
.matmul.matrix.csr) :
The method for function "%*%" and signature x="matrix", y="matrix.csr"
is sealed and cannot be re-defined
Execution halted
Is there some other way for us to handle such cases, or is this too aggressive behavior
on the part of setMethod?
