R help - May 2004 - Manova and specifying the model

Hi,

I would like to conduct a MANOVA. I know that there 's the manova() funciton
and the summary.manova() function to get the appropriate summary of test
statistics.

I just don't manage to specify my model in the manova() call. How to specify
a model with multiple responses and one explanatory factor?

If I type:
pcor.manova<-manova(isol+hcom+habarea+inclin+windprot+shrubcov+herbh+baregr+flowcov~pcor,
data=pcor.df)

I always get error messages like:
Error in manova(isol + hcom + habarea + inclin + windprot + shrubcov +  : 
        need multiple response

Can someone help me?

Thanks
Steffi

See the examples in ?summary.manova, please.

Y <- cbind(tear, gloss, opacity)

shows how to make a multiple response.
