Too many levels in unordered categorical variable error with high dimensionality column

[krishnateja614]

I recently stumble upon Ranger package and ideally it should be perfect for my project since I'm dealing with a column with high dimensionality (~4000, all right not so high dimensional :)) and Ranger handles that natively. The dimensions are not ordered in my column and hence I'm setting the parameter "respect.unordered.factors=TRUE" which is giving me the following error, "Too many levels in unordered categorical variable col_1. Only 63 levels allowed on this system. Consider ordering this factor" .I installed the R package from CRAN and not the dev version. Can someone help me how to resolve this error?. What I could gather was this error is present in the randomforest fortran package but I don't know what caused this error in my setting?

Which version of ranger are you using? With the newest CRAN version (0.6.0) this should work.

Thanks for pointing this out. Even though I ran install.packages("ranger"), it didn't update from 0.4.0 to 0.6.0 and packageVersion was still showing 0.4. I installed it manually with source files from CRAN and now that I'm on 0.6.0, the error hasn't occurred.Thanks for pointing this out.

Deal with same issue, using cpp_version, version 0.7.1
