Matrices without colnames.

[SamGG]

Hi,
I use ranger with matrices and I get the "Error: No covariates found." error.
In fact, my matrices don't have colnames, so the variable names are not defined.

ranger/R/ranger.R

Line 367 in dcaee8d

independent.variable.names <- colnames(x)

I think there should be a check here to compare the length of colnames(x) and ncol(x) and either raise an error or initialize the colnames with some values.
Let me know if it's unclear.
Best.

Thanks for your feedback. My bad, I didn't find it. I continue on #597.
