I understand that R 1.7.0 version (onwards) will solve the issue in #2655.
However, I still find the same error message. That is, a data matrix defined
outside the function containing the stepAIC() (alongwith glm()) is not passed
into the function. This data matrix is defined as one of the function

Error in model.frame.default(formula = Y ~ X4, data = A, drop.unused.levels =
TRUE) : 
        Object "A" not found

Greatly appreciate any advice.

Thank you very much.
