Biplab,
i'm not sure how to help you here, but this list pretty much runs on
plain ASCII (or, these days, utf-8) e-mail. for the most part, without
attachments. so, simply-formatted text, including code, with some
mechanism in the code to initialize any data structures (data frames,
matrices, etc.) needed for the example.
some of this is described in the posting guide

formatting your e-mail in this way will likely increase your odds of a
helpful reply.
cheers, Greg
