[R] svd error

[Spencer Graves]

      You haven't told us what you used to compute the pseudoinverse, 
but I can get that error message using ginv in library(MASS).  When I 
then typed "ginv" (without the parentheses, it listed the code, and I 
quickly saw "Xsvd <- svd(X)" [using R 2.0.1 under Windows 2000]. 

      hope this helps.

p.s.  The posting guide (www.R-project.org/posting-guide.html) can help 
you find answers to many questions like this yourself, in addition to 
improving your facility with language AND improving, I believe, your 
chances of getting a reply that actually answers your question.  In this 
case, if you are not using "ginv" in library(MASS) and the discussion 
above doesn't help you solve the problem otherwise, following the 
posting guide would have made it much easier for someone like me to 
provide a more useful answer.
