variables argument to predictions

[LamAdr]

Hi, this is adding support for variables argument for predictions function.

This line (111) adds the specified variables as a column to the output.

newdata.datagrid_explicit = list(variables.keys())

However, this is probably not how you want to do it ultimately. in R, all variables used in the model are present in the output, plus those specified in the variables and newdata arguments. This line will notably fail if newdata is present.

This line will notably fail if newdata is present.

I mean it will fail to add the variables as columns in the output.
