Is there a package somewhere that replicates the SPlus twoway() function? That
function models a 2-d data matrix, which may contain NAs, as
x[i,j] = grand.effect + row.effect[i] + col.effect[j] + resid[i,j]
I'm sort of resurrecting some ancient S code and it would be handy if a
twoway() function were available in R. I've googled and RSiteSearch'd, but
maybe there's something out there that goes by another name?
Thanks.

Why are they called 'speed' bumps?
