Depends on what was meant. If you just want the interval midpoints for plotting, you can do something like
endp <- c(0,.01, .025, .05, ... 2.5) # some manual assembly required here mid <- (head(endp, -1) + tail(endp, -1))/2 groupmid <- mid[group] plot(groupmid, VALUE) -pd > On 17 Jan 2022, at 16:34 , Bert Gunter <bgunter.4...@gmail.com> wrote: > > IMO, this is a bad idea.
