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 fields(the

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 if

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 ignoring

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. so it is
