[BioC] passing "main" argument to function plotPCA of affycoretools

[Mark W Kimpel]

I am trying to pass a "main" argument to plotPCA so that the title is 
customized. When I try to do this, I receive an error message "Error 
during wrapup: formal argument "main" matched by multiple actual arguments".

See my code and sessionInfo below.

Can I pass "main" as as an argument to plotPCA? Thanks, Mark


plotPCA(eSet, groups, groupnames, pcs=c(2,3), addtext = addtext, 
main="test title")
