Re: [R] Box Plot under GUI (R Commander/RKward)

something like this will get you going, assuming your data are in a dataframe called “qual”

# qual <- read.table(pipe("pbpaste"), header=T, sep='\t') boxplot(formula=Time~Distance+Season, data=qual)

Followup question from me:

i can’t see why
boxplot(formula=Time, data=qual)

should return the error "can’t find Time” “Time~" and “~Time" don’t help

Doesn’t that make the formula interface to boxplot broken for one-variable non grouped plots?

Best, t
