The solution to your problem is to not put prepend 'predict' with gstat::, but instead rely on S3 method dispatch. The actual, un-exported function called is gstat:::predict.gstat, but it is discouraged to call that directly. > > The session information is: > >> sessionInfo() > > R version 3.3.1 (2016-06-21) > > Platform: x86_64-w64-mingw32/x64 (64-bit) > > Running under: Windows 7 x64 (build 7601) Service Pack 1 > > > > locale: > > [1] LC_COLLATE=English_Australia.1252 LC_CTYPE=English_Australia.1252 > > [3] LC_MONETARY=English_Australia.1252 LC_NUMERIC=C > > [5] LC_TIME=English_Australia.1252 > > > > attached base packages: > > [1] stats graphics grDevices utils datasets methods base > > > > other attached packages: > > [1] myrpackage_0.0.0.9000 devtools_1.12.0 > > > > loaded via a namespace (and not attached): > > [1] tools_3.3.1 withr_1.0.2 memoise_1.0.0 digest_0.6.10 > > Is this a bug?
