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

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! -- View this message in context: http://www.nabble.com/Variogram-problem-tp16953929p16953929.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
