Hello, I have a dataframe: dd <- data.frame(b = c("chr2", "chr1", "chr15", "chr13"), x = c("A", "D", "A", "C"), y = c(8, 3, 9, 9), z = c(1, 1, 1, 2)) >dd b x y z 1 chr2 A 8 1 2 chr1 D 3 1 3 chr15 A 9 1 4 chr13 C 9 2
Now I want to sort them according column "b", but only its number is considered: b x y z 1 chr1 D 3 1 2 chr13 C 9 2 3 chr15 A 9 1 4 chr2 A 8 1 thanks jian [[alternative HTML version deleted]]
