the following code had been running well over the last months:
exam <- matrix(rnorm(100,0,1), 10, 10)
gg <- factor(c(rep("A", 5), rep("B", 5)))
mlmfit <- lm(exam ~ 1); mlmfitG <- lm(exam ~ gg)
result <- anova(mlmfitG, mlmfit, X=~0, M=~1)
Until, all of a sudden the following error occured:
Fehler in apply(abs(sapply(deltassd, function(X) diag((T %*% X %*%
dim(X) must have a positive length
I have not kept track of the changes in my R-version, so it might have
to do with that.
Now it is: R version 2.9.0 (2009-04-17).
Does anybody know more about this error? I would help me a lot!
Thank you very much!
