VariantAnnotation error with readVcf in Windows 7

Hi guys, I tried a sample with Variant Annotation's eadVcf. I ran the code successfully in Linux (OK I had
some warnings regarding " unpackVcf field '..': NAs introduced by coercion"). But when I tried the same
code in R3.0.0 in windows 7, I got the error message: > for(i in 1:length(vcflist1)){
         indexTabix(vcflist1[i], format="vcf")
         vcf <- readVcf(TabixFile(vcflist1[i]), "hg19", params)
         bgzip(outputfile, overwrite=TRUE)
         indexTabix(paste(outputfile,".gz",sep=""), format="vcf")
Error in (function (classes, fdef, mtable)  : 
  unable to find an inherited method for function ‘readVcf’ for signature ‘"TabixFile", "character",
"standardGeneric"’ What did I do wrong? Thanks a lot for the help! Ying
