Under R version 0.6.51  the following 

A_c(13,9,15,5,25,15,3,9,6,12)
B_c(42,24,41,19,27)
C_c(8,24,9,18,9,24,12,4)
D_c(9,12,7,18,2,18)
kaeufe_c(A,B,C,D)
region_factor(rep(1:4,c(10,5,8,6)),labels=LETTERS[1:4])
anova(lm(kaeufe~region))   

delivers

This is what I expected. Under RW 1.0.0 I get

Analysis of Variance Table

Response: kaeufe
Error in print.coefmat(x, digits = digits, signif.stars = signif.stars,
: 
        binary operator applied to invalid types

Am I doing something wrong or is this a real bug?

It's not happening on Unix... Does this happen when starting from a

It is also not happening on rw1000. Is your .Rprofile (if any) valid?
Try starting with --vanilla.

The submitter told me in private email that the problem disappeared
when starting with a blank workspace, so a critical function probably
had been overridden.
