[R] Variogram problem

[ONKELINX, Thierry]

Nicolas,

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

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

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.
~ Sir Ronald Aylmer Fisher

The plural of anecdote is not data.
~ Roger Brinner

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.

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!
