R help - Jun 2011 - Question on Manova

Hi all,

Is the Manova in R restricted to a certain amount of variables? I have currently
problems building a model with 47 variables.

Thanks a lot!

Best,

Veronika

Dear Veronika,

Is this the Manova() function in the car package? If so, there isn't a fixed
limit on the number of variables, although depending upon the size of the
data set, available memory, the conditioning of the problem, etc., you might
have a problem too big for it to handle. You don't specify whether 47
represents the number of responses or predictors or both, and without an
understanding of what you're trying to do it's hard to be definite, but
as a
general matter I wonder about the sensibleness of a MANOVA with 47
variables.

Best,
 John
