[R] Histograms of lots of variables

I forgot that win.metafile can only output one graph.  This will write
separate files:

lapply(3:20, function(.ind){
    win.metafile(filename=paste("file.", .ind, ".wmf", sep=''))
    hist(dataframe[[.ind]], main=paste("dataframe[[", .ind, "]]",
sep=''), xlab="")
