dear R developers:

may I suggest that you add to the various error messages that relate to
"non-conformable arguments" (e.g. matrix multiplication) or "not
multiple of"(e.g., comparison) the actual two dimension numbers that do
not match up?  something like

    Error in t(a) %*% vcov(reg.model) : non-conformable arguments
to
   Error in t(a) %*% vcov(reg.model) : non-conformable arguments (0, 5)

regards,

/ivo
