[R] Median in Classes

[Hecht Michael, F+E/ST]

Hello,

I've got a problem to find an effective calculation. 
There are x,y data and I want to build classes for 
the x values. For each class then I want to calculate
the median, N%-Quantiles, outliers, etc. for the 
corresponding y values and store all in a vector or matrix.

Is there a direct possibility to do this without 
storing to much temporary data?

Thank's in advance,

Michael Hecht
