[R] MANOVA / Hotelling's Test

Hi everybody ...

I have to perform Hotteling's T^2 Test - more generally a MANOVA - on a
set of data.  Is there a (simple?) possibility to do it in R? 

The somewhat obvious way to do it would be

> summary(aov(Y ~ x1 + x2 ... + xn)) 

where Y would be a two-column matrix. 

But this does not work in any possible combination of matrix or factor
dimensions! Is it principally not possible to perform modelling of
multivariate data using the "~"-operator? 

I'm using R 0.62.2 on Linux 2.0.25. 

Many thanks in advance ...
