[R] Different result of multiple regression in R and SPSS

[J.]

I finally got the same result by converting "gender" variable as numeric, and
standardize it.
I guess SPSS automatically doing the same thing when doing analysis.
But, it still is not clear to me how I can interpret "standardized
categorical (dummy coded)" variable.
I'd rather stick to use R.
Thanks for all the comments and advice.

Jay
