Dear GeoR-er, If I use the variog function in the latest release of geoR, the first lag is always ignored. For instance, if you read in geodata, calculates the variogram using the variog function and give in a uvec like uvec=seq(0,max,by=2.44), it only starts giving results from distance=4.88 and ignores 2.44! This wasn't the case in former versions of geoR. Is this done on purpose? Why? Tnx for your help, Dave Nys K.U.Leuven Laboratory for Forest, Nature and Landscape Research Vital De Costerstraat 102 B-3000 Leuven Tel. +32 (0)16 329751 Fax. +32 (0)16 329760 email: Dave.Nys at agr.kuleuven.ac.be
