R help - Jan 2006 - Application of R and MNP

Dear all,

I'm a new user of R and MNP.  Would anybody advise me what I have done wrong
to the input or data.  When I add the R7, it said that there is an error
"SWP:singular matrix".  I can add up to R6 only.  Copy of the R
console is
attached for your reference.

Thanks.

Andy

Dear Andy,

You appear to have 7 observations and 8 explanatory variables in the model.
You'd be in trouble even if this were a linear model fit by least squares.
Moreover, each observation has a different value of the response variable --
that, is the response has 7 levels. Did you really intend to do that?
Perhaps it would help to know what you want to do with these data.

I hope this helps,
 John
