A reading of the help page for the function using ?boxplot would be 
enlightening, taking note of the 'range' argument relative to the whiskers, 
which defaults to 1.5.

The See Also on that help page points you to ?boxplot.stats "which does the 
computation" and has additional detail. Both pages list references.

If all else fails, since R is open source, you can always look at the source 
code for both functions to follow exactly what is done.
