[R] Quantiles in boxplot‏

[René Brinkhuis]

Hi,

I have a simple question about quartiles in R, especially how they are calculated using the boxplot.
Quartiles
 (.25 and .75) in boxplot are different from the summary function and 
also don't match with the 9 types in the quantile function.
See attachment for details.
Can you give me the details on how the boxplot function does calculate these values?

Cheers,
