Dear all, I was trying to use the function fit.variogram.gls from gstat package, and I got the error below: "Error in gamfn(h0, theta) : could not find function "gamfn""
Below some lines of code that trigger the error: library(gstat) library(sp) data(meuse) coordinates(meuse) = ~x+y fit.variogram.gls(log(zinc)~1, meuse[1:40,], vgm(1, "Sph", 900,1)) My sessionInfo(): R version 3.4.2 (2017-09-28) Platform: x86_64-redhat-linux-gnu (64-bit) Running under: CentOS Linux 7 (Core) Matrix products: default BLAS/LAPACK: /usr/lib64/R/lib/libRblas.so locale: [1] LC_CTYPE=en_GB.UTF-8 LC_NUMERIC=C [3] LC_TIME=en_GB.UTF-8 LC_COLLATE=en_GB.UTF-8 [5] LC_MONETARY=en_GB.UTF-8 LC_MESSAGES=en_GB.UTF-8 [7] LC_PAPER=en_GB.UTF-8 LC_NAME=C [9] LC_ADDRESS=C LC_TELEPHONE=C [11] LC_MEASUREMENT=en_GB.UTF-8 LC_IDENTIFICATION=C attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] gstat_1.1-5 sp_1.2-5 loaded via a namespace (and not attached): [1] zoo_1.8-0 compiler_3.4.2 tools_3.4.2 xts_0.10-0 [5] spacetime_1.2-1 grid_3.4.2 FNN_1.1 intervals_0.15.1 [9] lattice_0.20-35 The same is happening also under Fedora 27 (Workstation Edition).
