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)
