Dear R users, Problems with a .Call("logit_link",...) led me to the following test on virgin sessions of R2.15.2, R2.15.3, R3.0.0, R3.0.1 (Precompiled windows binaries in all cases) ==== begin code =========getNativeSymbolInfo("logit_link") ==== end code =========This works as expected on R2.15.2 and R2.15.3, but not on R3.0.0 and R3.0.1 where I get the message Erreur dans FUN("logit_link"[[1L]], ...) : no such symbol logit_link Adding the argument PACKAGE="stats" has no effect. Same error message for other functions from the stats DLL, but not for functions from the base package [e.g. getNativeSymbolInfo("dqrqy")]. I see that the examples in ?getNativeSymbolInfo have disappeared after R2.15.3, but I see no other changes in that documentation that could explain the change in the results. Other information (similar for all versions of R): ========= > sessionInfo() R version 3.0.1 (2013-05-16) Platform: x86_64-w64-mingw32/x64 (64-bit) locale: [1] LC_COLLATE=French_France.1252 LC_CTYPE=French_France.1252 LC_MONETARY=French_France.1252 [4] LC_NUMERIC=C LC_TIME=French_France.1252 attached base packages: [1] stats graphics grDevices utils datasets methods base loaded via a namespace (and not attached): [1] tools_3.0.1 ========== Any insight ?
