0.485 for X and Y respectively. These values do not differ significantly
from 0.5.

Dear R-Users,
in the configuring file of R on the supercomputer I am using I found a line
--disable-openmp (version R 2.13.1)
Is there a possibility to enable this when I let run a BATCH file via R CMD?
Thanks for comments!

Hi guyz,
I have serious problems with an algorithm I let run on a supercomputer:
You find the functions under the following URLs:
simuFunctionCaller: http://pastebin.com/6gw2fJFb
calls Function simuFunctionNBM (http://pastebin.com/QeJDUnqx)

Hi guyz,
I have run my algorithm in R (see http://pastebin.com/q84Tujfg) and got the
following error:
Error in ar.ols(x, aic = aic, order.max = order.max, na.action = na.action, :
'order.max' must be 'n.used'
I am pretty sure, that the error comes from the NeweyWest function in line 45,

Hi Rich,
I do not know what u really want, because it seems to me, u want to calculate
the mean of all rows, where the chemical is Arsenic??
But try this to get a little more inside:
mean(chemdata$quant[chemdata$param==Arsenic])
The vector chemdata[chemdata$param==Arsenic,] is a logical
Dear R users,
I am using R right now for a simulation of a model that needs a lot of
memory. Therefore I use the *bigmemory* package and - to make it faster -
the *doMC* package. See my code posted on http://pastebin.com/dFRGdNrG
Now, if I use the foreach loop with the addon %do% (for sequential
