R help - Apr 2008 - Variogram problem

Hello, 

I'm french and I have some difficulties in carry out the semiones under R
with an aim  to carry out an interpolation by krigeage. My goal is to obtain
a chart of the distribution of precipitations/temperatures in Europe
starting from 73 different stations (and, of course, distributed irregularly
on the chart, where use of the krigeage). Here, I carried out this to test
to obtain semivariogram spherical by groping:

x<-ts(rnorm(73)) 
cs1<-corSpher(form=~x) 
y<-Variogram(cs1,2628) #2628 corresponding to the " distance"
described in
l' helps, that is to say the number of station* (the number of station -1)
/2.

But  there does not go it misses apparently much d' information. Having
begun under R for approximately one month, I have not controlled all his
language yet, I am completely lost. Thank you for your answers, your
assistance would facilitate the task largely to me!

Nicolas,

I think you better have a look at the gstat package.

install.packages("gstat")
library(gstat) 
example(gstat)
?variogram
?krige

HTH,

Thierry

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to
say what the experiment died of.

The plural of anecdote is not data.

The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of
data.

PLEASE do read the posting guide
http://www.R-project.org/posting-guide.html
and provide commented, minimal, self-contained, reproducible code.

Thanks for your help, It is definitely that it is needed to me in finale, I
therefore did not use the package check. I am going to try to understand
step how is that now.

Still thanks for your help!
