r - Subset rows which have a column inside numeral interval -

-
i subset lines have "chr" column 1 29, in "cnv1" dataframe. i tried it: cnvk <- cnv1[cnv1$chr==1:29,] but not lines have 1,2,3...29. cheers! try cnvk <- cnv1[cnv1$chr %in% 1:29,] or cnvk <- cnv1[cnv1$chr>=1 & cnv1$chr<=29,] (the latter might quicker if you're checking against large range of values)
