Doing Mathematica Quantile[] function in R
Hi all,
I am an R newbie trying to do some calculations I do in Mathematica in
R on a GNU/Linux system.
The main thing I am interested in doing is taking a 0.999 quantile on
a data set in a file who's data is normally distributed, say foo.csv.
e.g in Mathematica if I have something like this :
a=Import["foo.csv"]
b=Transpose[a][[1]]
Quantile[b,0.999]
In R I can load all the data

The old question: R vs MATLAB vs Mathematica vs ...
Hi,
This question seems to be old, however I am asking it from a different point
of view.
R introduces itself as a 'statistical' language and environment. There are
many discussions about comparing R to MATLAB or mathematica (or other
similar software). It seems to me that these other software have a broader
range of applications. For example, in Mathematica one can solve a partial

Calling R from c in Windows XP
I'm searching for answers to four questions (I've been searching the net for
hours...)
In Windows XP, is it possible to call R functions from a c program? (I've

If so, is there a simple example to get started using gcc with R-2.10.0?
If so, is it possible to write a simple interface using a c dll to call R

Mathematica now working with Nvidia GPUs --> any plan for R?
Dear All,
I just read an announcement saying that Mathematica is launching a
version working with Nvidia GPUs. It is claimed that it'd make it
~10-100x faster!

I was wondering if you are aware of any development going into this
direction with R?
Thanks for sharing your thoughts,

Hook into Coercion Framework for data.frame
Hi,
I am looking into a way to hook into the R coercion framework to allow
me to convert table-like data stored within a COM object into a
data.frame.
Some of our COM objects have their own table-like data storage, and from
R's point of view it's an object (EXTPTRSXP) decoarated with a sepcial
symbol so we can easily identify it.
