There are lots of slightly different
definitions of quartiles (more generally
of quantiles) and packages
and sometimes commands within packages
differ in what they use. This could
easily account for some apparent
discrepancies.
See for example
Rob J. Hyndman; Yanan Fan. 1996.
Sample quantiles in statistical packages
The American Statistician, 50(4) 361-365.
