I have a dataframe like this: V1 V2 V3 1 1 3423086 3423685 2 1 3467184 3467723 3 1 4115236 4115672 4 1 5202437 5203057 5 2 7132558 7133089 6 2 7448688 7449283 I want to change the V1 column and add chr before the number. Just like this: V1 V2 V3 1 chr1 3423086 3423685 2 chr1 3467184 3467723 3 chr1 4115236 4115672 4 chr1 5202437 5203057 5 chr2 7132558 7133089 6 chr2 7448688 7449283 Is there a way to do this in R? The regex pattern "^" (outside any character-class brackets) represents the point just before the first character of a "character"-class item (aka "string" in other computer languages)
