Dear Sergio,

The Anova() function in the car package can perform MANOVA with a multivariate linear model fit to unbalanced data by lm() -- see the examples in ?Anova. I'm not sure what you mean by "avoiding NA values," however. With the default na.action, which is na.omit, lm() will perform a complete-case analysis, omitting cases with NA for any variable in the model.

I hope this helps,
