good source for explaining input and output parameters of R functions
Hello,
thank you all for answering my previous Qs.. I have a new Q:
I am wondering is there good source for explaning input and output
parameters of R function?
In that aspect, I found the help documents in R is not that helpful:)
I am struggling with trying to understand what some of the returned value
means..
for example, for surf.ls() function, the help in R only describes 3

krige in gstat() package
HI,
I wonder does anyone have experience with doing sequential gaussian
simulation with krige() function in gstat?
I find it VERY slow compared to use krige() to achieve kriging function
itself.. I wonder why, is that because it has to model the variogram, and
do the kriging separately for each point to be simulated?
so it would be N times slower to achieve the simulation than the kriging

locfit
Hi, I have a Q on locfit,
E.g., I have an input data set of the form {(x, y, v)} , (x, y) is the
location in a 2D space, v is the value at that location.
I am wondering for the output of locfit(), if a given point (x, y) is in
the input data set, is the value at (x, y) going to be the exactly same
as the input? or it depends on the local fitting function?
does my Q make sense?
Thanks a lot in

Asterisk not accepting user input .. pls help !!
Hi guys,
I currently have a sip proxy server (sip express router) which
registers the sip phones. I need to add voice mail capability, i.e.
sip express router will forward all incoming calls to Asterisk if the
user does not pick up the call in 15 seconds.
The voicemail recording stops when the user hangs up. However, the
recording does not end if the user presses the # key, i.e. it is

Asterisk voicemail
Hi guys,
I'm new to Asterisk, so I'm hoping someone can guide me :-)
Currently, I am having the configuration as follows :
PSTN -> Cisco router -> Sip Express Router -> Asterisk Voicemail
I'm able to get the part from PSTN to Sip Express Router working, but
I can't integrate Asterisk with Sip Express Router (SER).
Basically, SER does all the registering and forwarding

kriging in R
Hi, all,
Have anyone used kringing included in R? How is it?
Does it handle anisotropy data well?
How does it compare with Kriging in Arc/Info? or other geostatistics
software customized to do kriging or other geostatistics functions?
I tried Easykriging, a geostatistics tool developed for Matlab. It has
very nice GUI, but it does not provide library which i can call in my programs.
