Hi I'd like to remove a leading "3" if my number is 7 digits long, if it is only 6 I don't want to anything. I think this should be possible with a 1-liner using sub() but I am not sure how to define the number of characters following the leading one.
For example my vector: a <- c(3593857,384723,4395843,3398374) with sub("^3","",a) I also remove the leading from the second element which is only 6 digits long. So how to restrict that using sub? The final result should be a <- c(593857,384723,4395843,398374) Any suggestions?
