R error in glmnet: NA/NaN/Inf in foreign function call

Question

I am trying to create a model using glmnet, (currently using cv to find the lambda value) and I am getting an error NA/NaN/Inf in foreign function call (arg 5).

Answer 1

Chars datatypes that are converted to factors cannot be supported for cv.glmnet, as stated above, can't handle NA's. Either use as.numeric or as.double.
