Step function for variable selection is not working

Question

I am trying to do a variable selection using the step() function in R. But it keep getting an error. Then I found out that now there is no basic step() function like previously. There is a step function in the lmerTest package for mixed models.

Does anyone know an alternative function for this ?

Here is a screenshot of the error:

Apparently stats::step (I assume it is the function you want to use) is masked by another package (probably lmerTest).

Did you try with the package name?

stats::step(regmodel, direction = "forward")
