dotchart(precip[order(precip)], main = "precip data")

## Old ("wrong") version of dataset (just name change):
precip.O <- local({
p <- precip; names(p)[names(p) == "Cincinnati"] <- "Cincinati" ; p })
stopifnot(all(precip == precip.O),
match("Cincinnati", names(precip)) == 46,
identical(names(precip)[-46], names(precip.O)[-46]))
