i'm in the midst of using R for a PVA/matrix project. my math skills are
lousy and programming skills are worse. to deal with an error that i
couldn't solve, i changed a parameter that used a new part of a routine
in our PVA package's code:
else if (ES == "ParDraw") {
require(MASS)
(previously, ES was "MatrixDraw" and MASS wasn't called for)
now, i get the following error:
Error in apply(parmat, 1, mean) : dim(X) must have a positive length
there is no code in the PVA package routines that has a line that says
"apply(parmat, 1, mean)" or parmat or the format "(____, 1, mean)".
that's why i think the error has something to do with MASS. i tried to
update MASS, but had problems with that. i've searched for parmat. i
looked through the MASS documentation for parmat. i don't know what it
is or how to change whatever is affecting parmat.
i'm using RGui from version 2.6.0 on an XP machine.
sincerely,
john
