[R] Logistic Regression in R (SAS -like output)

[Harsh]

Hello useRs,

I have a problem at hand which I'd think is fairly common amongst
groups were R is being adopted for Analytics in place of SAS.
Users would like to obtain results for logistic regression in R that
they have become accustomed to in SAS.

Towards this end, I was able to propose the Design package in R which
contains many functions to extract the various metrics that SAS
reports.

If you have suggestions pertaining to other packages, or sample code
that replicates some of the SAS outputs for logistic regression, I
would be glad to hear of them.

Some of the requirements are:
- Stepwise variable selection for logistic regression
- Choose base level for factor variables
- The Hosmer-Lemeshow statistic
- concordant and discordant
- Tau C statistic

Thank you for your suggestions.
Regards,
Harsh Singhal
