It is possible to call R functions from .NET by using a .NET wrapper over
the R (D)Com server. http://www.nabble.com/file/p25682136/RFromCsharp.zip

You can try to hunt for it in the findbestsplit Fortran subroutine. It

Hi Tal,
The Wiki is a great idea! Alas I'm not that familiar with setting up
Wikis. Any idea how to practically approach this?
I'm currently a bit in a hurry, as I have to give the introduction

the week, but I'll continue to d

Hi Joris.
This is a wonderlful idea.
I never came across such a document, but assembaling it sounds very good.
What do you think about organizing the work of collecting (by R members and
maybe your students) the error massages and code into some wiki page? (maybe
on the R wiki)
It could be a gre
Hello members of the R-help group.
I am trying to run multiple occurences of R (through the distributed
computing of Condor), and have all of them write their output into one

It is similar (I believe), to running R several time on the same machine,

Although I can't answer all your questions, I can give some suggestions.
I will assume you know how many years of data you
have. Suppose it is 2004 through 2009.
In each input file, the columns must have names,
so I will assume there is a column named "Month".
I am not sure if you want

Luis,
I don't think that you want log() in fn. Try it with
pdf=-sum(dnorm(x, media, st, TRUE))
(and note the x, rather than xx).

1. A common way of doing this is cut:

Levels: Pre Post
We don't actually need right=TRUE as its the default but if you omit
it then it can be hard to remember whether the right end of intervals
are included

Hi,
You can use list.files() of Sys.glob to get a listing of all the files
in a certain directory, e.g. to get all ".R" files and source them:
for(f in Sys.glob("C:/Documents and Settings/lma/*.R")) source(f)
