Hi,
I am new to R.
and even though I've made my code to run and do what it needs to .
It is taking forever and I can't use it like this.
I was wondering if you could help me find ways to fix the code to run
faster.
Here are my codes..

What I am doing is this.
I pick a column and make up a new column Y with values associated with that

contribution offer: df() for non-centrality != 0
Hi R-devels,
I noticed that for the scheduled R 2.3.0,
there is still no function df() for
non-centrality != 0.
Easter is quickly approaching, so as my little
gift, I would like to offer you some code to fill
this gap:
After excluding some "unusual" cases,
it amounts to differentiating the corresponding
function pnf() --- which in turn leads to the
function dnbeta() already available

speeding up "sum of squared differences" calculation
All,
I am using a sum of squared differences in the objective function of an optimization problem I am doing and I have managed to speed it up using the outer function versus the nested for loops, but my suspicion is that the calculation could be done even quicker. Please see the code below for a simple example. If anyone can point out a faster way I would appreciate it greatly.
Thanks,

Difficulties with egcs-1.0.3 on RedHat 5.2?
Some machines in our department use RedHat 5.2 Linux but, to maintain
consistency with other machines, the compilers as from egcs-1.0.3, as
shown below. When I compile R-0.63.3 on these systems I can't pass
the tests in "make check". The base-Ex.R file stops execution with
the error shown below.

Excell files clobbered by Samba log files
I have a couple Samba servers running 2.0.4a on Solaris 2.6. They
generally give me no trouble, and have been stable for a long time.
I'm in the process of qualifying 2.0.7, but feel no great urgency
to upgrade.
However, one day last week several users reported trouble getting
to their files. I changed the debug level several times during the
day to try to diagnose the problem. With

R: chi-Squared distribution in Friedman test
Hi,
pchisq -> distribution function
dchisq -> density function
pval is the area under the curve, to calculte it you
use distribution function which is the integral of
density function. See:

f(x) density function
F(x) distribution function =Pr(X<x)= integral(f(x))

Samba crashing word and excell?
I am having some trouble with Samba. It was working fine on an old server with 3.0.21.
Now I have updated to 3.0.28 (via 3.0.25) and a bigger fatter faster server.
There are two problems. Firstly the new server seems slower than the old one, and some users
are experiencing intermittent data loss via MS apps such as Word or Excell crashing.
The system runs on Arch Linux, with a slightly
