Extracting data from .zip file in WINDOWS version of package

I am building a R-package for Genetics analysis. The accepted data is in pedigree (.ped) file format. To load the data (say CAMP.ped) from "data" directory, I have a function "CAMP.R", which does the job. The package builds successfully in Linux (.tar.gz) and the data loads successfully by "data(CAMP)". However, when I build the package in WINDOWS, the data directory is zipped, and the command "data(CAMP)" gives an error - Error in readGenes(gfile = "CAMP.ped",....) Genotype file CAMP.ped does not exist. While debugging "data(CAMP)", I found that only the file "CAMP.R" is extracted temporarily, and not the file "CAMP.ped" - which causes the error. Linux version does not face this problem as the data directory is not zipped.
Well, not zipped by default: it can be zipped.
Could you please suggest a way around for this problem?
You need to read the `Writing R Extensions' manual and set the appropriate option in the DESCRIPTION file. Search for 'ZipData'
