R help - Jul 2005 - multivariate regression using R

Does anyone know if there is a way to run multivariate linear regression
in R?  I tried using the lm function (e.g., lm(dv1, dv2~iv1+iv2+iv3),
but got error messages.  Is my syntax wrong, or do I need a particular
package?

 

Thanks,

You need a matrix response: lm(cbind(dv1,dv2)~iv1+iv2+iv3) should do.
There is an anova() method for comparing the resulting "mlm" objects.

And yes, your syntax is wrong: you're calling lm with 2 arguments, dv1
and dv2~iv1+iv2+iv3.
