[R] Doubt about aov and lm function... bug?

[Jose Claudio Faria]

Hi Peter and Rolf,

Many thanks for all!

The "bug" was just found: it is related with the package AlgDesign!
(and I've been loading it from Rprofile.site already for a long long time). :-(

See below:

> aov(Sepal.Length ~ Species, data=iris)

Error in parse(text = x) :
  unexpected symbol in "Sepal(Sepal.Length+Species)Length"

I wonder it is really a small bug. Do you agree?

All the best,
