Read zip file without unzipping in R

The following R function is modified from Joshua Ulrich's post in stackoverflow. An argument FUN is added for specifying what R function would be employed to process the file handler.

read.zip = function(file, FUN=read.table, ...) {
  zipFileInfo = unzip(file, list=TRUE)
  if(nrow(zipFileInfo) > 1)
    stop("More than one data file inside zip")
  else
    FUN(unz(file, as.character(zipFileInfo$Name)), ...)
}
