Rerun your code and as soon as the error occurs type:  

> traceback()
 

This will show more information on where the error is actually occuring. If this does not clear it up for you, then send more of an example of what you are doing along with the output of traceback (see the link at the bottom of all r-help messages for more information on heow to get good answers from the group) and we may be better able to help.

Subject: [R] parmat error from MASS?

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
