Hi,

I'm running R 2.11.1 on Windows 32-bit. I fitted a glm to a "large" data set
with no problems (i.e., nothing is wrong with the created glm object).

However, when I try to use the "effects" package to plot the effects I get
the error message shown below. I get the same message if I try to plot a
single effect. Any idea what could be wrong here?


glm.eff <- allEffects(glm1)
plot(glm.eff)


Error in apply(mod.matrix[, components], 1, prod) :
  subscript out of bounds
In addition: Warning messages:
1: In `[<-.factor`(`*tmp*`, ri, value = c(1, 1, 1, 1, 1, 1, 1, 1, 1,  :
  invalid factor level, NAs generated
2: In matrix(apply(as.matrix(X.mod[, facs]), 2, mean), nrow =
nrow(mod.matrix),  :
  data length exceeds size of matrix
3: In matrix(apply(as.matrix(X.mod[, covs]), 2, typical), nrow =
nrow(mod.matrix),  :
  data length exceeds size of matrix

Thanks,
Lars.
