A long time ago thomas noted:

TASK: Matrix multiply problems
STATUS: Open
FROM: <thomas@biostat.washington.edu>
Both of these used to work and seem useful and harmless (and work in S):
R> matrix(1,ncol=1)%*%c(1,2)
Error in matrix(1, ncol = 1) %*% c(1, 2) : non-conformable arguments
R> matrix(1,ncol=1)*(1:2)
Error: dim<- length of dims do not match the length of object
----------------------------------------------------------------------
I have fixed both of these. In the second case all binary ops now
behave in this manner. In the first case only %*% has been "fixed".
