parallel max, min, and median of dataframe columns
...quot;, add=TRUE) But these don't: > st <- c(1:19) > segments(st, pmax(data_frame), st, pmin(data_frame)) (no, I haven't tried to put in the median points yet) I can plot them individually with > segments(1, max(data_frame[,1]), 1, pmin(data_frame[,1])) > points(1, median(fly_ash[,1])) but that's a bit tedious. Is there a better way of vectorising these columns such that they will work with pmax? Is there something like a pmedian? Regards, Hazel Jenkins
