Weighting factor

Hi everyone,

I would like some package of R or any help to solve the next problem
with a weighting fatcors:

Giving a data matrix with dichotomous (2 or more) variables in columns
and individuals in rows, and also a theorical distribution of the
dichotomous variables I would like a row weight (one per individual)
that transform the real distribution of variables to the theorical
distribution.

Thanks in advance and best regards,
