Hello:
I am plotting some data using the box and whisker plot.
What function?
However, I only want to plot the median, max and min, as I only
have these values and not the quartile values.
You could just read the help page for bxp and send it values that
yield what you want to see.
?boxplot.stats
?bxp
Or ... using lattice::bwplot you can alter the stats function in
panel.bwplot.
?panel.bwplot
It seems R arbitrarily constructs the box margins to be halfway
between the median and the max/min.
Not exactly ... and not at all arbitrary. Those are at the Q1 and Q3
values.
How do I make the box and whisker plots without the box values?
Thanks,
Michael
