OO programming in R
Dear,
I'm looking for some examples on OO programming in R. I have the
programming manual with explanation on UseMethod and NextMethod but I
miss some practical examples to get me going (I hope). I searched the
web but could not find a good independent tutorial on this.
Any suggestions are welcome,
Kris

Use of variables to reference to objects
Hi,
I'm new to R and looking for a way to use a variable to reference to an
object.
I'm plotting several graphs on top of each other and want to do this by
a for loop. The field I want to graph have names like a1,a2,a3, ...
I can't figure out how to get this working:
It should look like this:
lines(spectral$Wavelength,paste("spectral$a",j,sep=""),col=j)

Can't find nls()
Hi,
I looked for the nls() function and couldn't find it. In the refman.pdf
it's mentioned as part of the nls package which I cannot find and I also
read something about the MASS package, also impossible to find for me.

geoR vector length error
Dear,
we have a problem with geoR. We try to read an ASCII table (x,y,z) with 40000
lines. With read.geodata we get the error:
Error in vector("double", length) : cannot allocate vector of length 799980000
We can read the file without any problem with read.table, but trying to
convert it to the geodata class gets the same error.
Any help/tips would be appreciated.
Kris, Dave

Contouring irregular xyz data via TIN
Dear,
I have XYZ data available in a MySQL database. I get it out, can plot
the data with the plot() function, load it into a geoR datastructure.
But what I actually would like to do is a simple contouring of the data
based on a no Kriging interpolation such as TIN based.
I know the first thing I shold do is interpolate a full matrix for the
region I have my points for, then contour should

R should recognize that some dates are not available...(NA). You can

readcsvIts() to create irregular time series

Thanks for the previous tips about 'its' for importing the following

tsdiag and tsStructure for np,ns,nt and nl determination
Hi R-Helpers,
I'm dealing with the STL procedure and trying to apply the tsdiag and
StructTS onto the ts object to analyse the different parameters which
need to be set. How can I use the tsStructure & tsdiag to create a
seasonal, trend and cycle subseries plot so that I can select & analyse
the correct np,ns, nt and nl?
The problem is that too much signal goes into the seasonal

STL- TimeSeries Decomposition
Dear R Helpers,
Currently I'm working with the ts package of R and created a TimeSerie
from pixels extracted from satellite imagery(S10 NDVI data, 10 daily
composites). I'm trying to decompose this signal in different signals
(seasonal and trend).
When testing out the STL method is says => Only univariate timeseries
are allowed, but the current Timeserie I'm using is univariate!

interpolation methods
Hello all,
I want to interpolate some data i prepared in GRASS, so I'm looking for what
interpolation methods are available for R. In GRASS I can do Splines with
tension and IDW. I'm looking for something like multiquadric equations. Is
there any function/package available fo rthis?

Using pipe for input data
Hi.
I have asked this question before and Aaron J. Mackey and Tony Plate gave me
some great insight but I still can't figure out how to do what I am trying
to accomplish. So let me ask again...
What I am trying to do is to make R read data from pipe (stdin).
Say I have following files on my directory

using flash to connect to ICECAST 2.3.2
Starting on friday I download icecast 2.3.2 and compiled it on SLES10.
Very soon I was able to use ices to stream an mp3 file to a mp3
(phonostart, foobar) client via Icecast.
But my flashplayer, which was able to get streams from icacast1, was not
able to full fill his job.
I did reseaches on the net, hour for hour, found a lot of stuff. Also
some changings in format_mp3.c.
But with no success.

Hi,
dovecot provides POP and IMAP services.

Would be nice if it also could offer an RSS-Feed for a mailbox,
giving a summery of sender/subject/date and maybe the first lines

CBQ and/or HTB help needed
Ok, this has been kicking my @$$ for weeks. I'm trying to get some
kind of bandwidth shaping working on my server. I need to throttle ftp
down so as not to suck up all the available bandwidth. I had cbq
working on the old server (an ancient RH 6.2 box) so I figured I'd just
move the config over and get cbq.init from sf.net and it should work.
Unfortunately it doesn't. At least
