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
