Error: object is not a matrix
I have updated to R 1.5.1, but now get a new error, which appears to have the same cause:
AK.df <<- read.table("foo.data", col.names = c("Y","P","A","B","CLongFactorName"))
AK.df$P <- as.factor(AK.df$P)
attach(AK.df)
AKanova.out <- aov(Y ~ A * B * CLongFactorName + Error(P + P:A + P:B +
P:CLongFactorName + P:A:B + P:A:CLongFactorName + P:B:CLongFactorName + P:A:B:CLongFactorName), data=AK.df) Error in eval(expr, envir, enclos) : couldn't find function "Error" I can avoid the error by either of the following steps: 1) replace "CLongFactorName" with the shorter label "C" 2) reduce the number of terms in my Error formula.

I have reproduced this error in a number of ways, and the only common characteristic I can see to my actions is that the length of the call to 'aov' is always too long: either one of the variable names is too long, or I include too many error terms, etc...).
A similar error was fixed in 1.5.0. Which version are you using?
o aov() and model.tables() were failing on multistrata models with
excessively long Error formula. (PR#1315)
