R: mlogit - Error 'dimnames' applied to non-array
I am trying to analyse choice data from a discrete choice experiment. I get the following error when running the mlogit()-function:
Error in dimnames(P) <- dimnames(Xb) <- list(attr(y, "chid"),
names(y)) : 'dimnames' applied to non-array
Here is a code that replicates the Error:
test <- data.frame(
id = rep(1:10,each=100),
instance = rep(1:500,each=2),
choice = c(rep(c(1,0),150),rep(c(0,1),200),rep(c(0,0),150)),
rating = sample(1:4,1000,replace=T),
brand = sample(c("A","B","C"),1000,replace=T),
price = sample(1:5000,1000,replace=T)
)
mlogitformat.test <- mlogit.data(data=test, shape = "long", choice = "choice", id.var = "id", alt.levels = "instance", varying = 4:6)
model.test <- mlogit(choice ~ 0 + rating + brand + price, mlogitformat.test)
What am I missing?
