[R] Stepwise selection and F-enter anf F-remove values

[Simon Blanchet]

Hello,

I'm actually using the "Step" procedure in R for multiple regression analysis.
I'm using the stepwise selection which alternates between forward selection 
and backward elimination (direction "both" in the step procedure).
I would like to know which F-levels R is using to enter and then to remove 
variables?
I also would like which is the procedure to change such levels? For 
instance, how to use a critical/levels of 0.05/0.10?

Many thanks in advance!

Very sincerely,

Simon Blanchet
