With Ken Higbee's help I was able to find -mtest()-. I'm still not sure
how to use it.
I have a 2 by 2 anova with insignificant main effects but a signifcant
interaction. I like to explore any differences between cell means. I not
sure how to specify the matrix for -test[matrix name]-. I suppose it's
the design matrix but when I use the "simian" approach and try different
things I get the error message that the matrix is nonconformable.
Any help would be appreciated.
Thanks,
Jim Seward
