I have a number of variables in a data.frame in R, called Offshore, EA19, NON_EA19 and many more. What's the easiest way to put a "P_" in front of every variable's name, so that they're called P_Offshore, P_EA19, P_NON_EA19?
Preferably in dplyr.

If you want to rename all the variables, you can use `mtcars %>% setNames(paste0("P_", names(.)))` if you like pipes – talat May 16 '17 at 13:02

2An alternative: `names(mydf) <- sub("^", "P_", x = names(mydf))` – KoenV May 16 '17 at 13:05

@docendo discimus, since there is only one single variable for which I do not want to change the name, this is a well enough approximation. – Laubsauger May 16 '17 at 13:31
