Pre-model Variable Reduction

Hello All, I am trying to carry out variable reduction. I do not have information about the dependent variable, and have only the X variables as it were. ... I looked for other R packages that allow me to do variable reduction without considering a dependent variable. I came across 'dprep' package but it does not have a Windows implementation.
I doubt that you will find what you are longing for, but: There is a Windows version available at the "Homepage of the drep package" at <http://math.uprm.edu/~edgar/dprep.html>. This version 2.0 can be loaded without errors into R 2.8.0 though it appears not to be fully compliant with the tests on CRAN.
Moreover, I have a dataset that contains continuous and categorical variables, some categorical variables having 3 levels, 10 levels and so on, till a max 50 levels (E.g. States in the USA). Any suggestions in this regard will be much appreciated. Thank you Harsh Singhal Decision Systems, Mu Sigma, Inc.
