vector fragment
Dear R users: I have got a simple question that has been bothering me for a while. Given a certain character vector, I would like to get in a separate vector a fragment of text, in this case the 3rd and 4th letters of each element. So, if: v<- c(“stratosphere”, “mesosphere”, “troposphere”) I want to obtain a different vector like this: c(“ra”, “so”, “op”) Thanks in advance for your help Jonas [[alternative HTML version deleted]]
