[R] Problem with effects package

[Lars Bishop]

ok. Here's an example:

R version 2.11.1
effects_2.0-10

var1 <- c(25631.9392, 2521.2590,  6656.6516,  1362.5997,  6369.9818,
27253.4223,  2073.1909,  9959.3792,
          3318.2500, 15323.8103, 11583.8717,  3054.5558,   625.6597,
2500.0000, 11996.2271)
var2 <- as.factor(c("B:=500", "B:=500", "B:=500", "B:=500", "B:=500",
"B:=500", "B:=500", "B:=500",
                   "B:=500", "C:750-1000", "C:750-1000", "B:=500",
"B:=500", "B:=500", "B:=500"))

glm1 <- glm(var1 ~ var2, family = Gamma(link = "log"))
summary(glm1)
library(effects)
plot(effect("var2", glm1))

Error in apply(mod.matrix[, components], 1, prod) :
  subscript out of bounds
Error in plot(effect("var2", glm1)) :
  error in evaluating the argument 'x' in selecting a method for function 'plot'
