It is used when mapping external entry points to R symbols in that package: the latter must not clash with other R objects in the namespace, and this is why the prefix is added (in the NAMESPACE file, at # Refer to all C/Fortran routines by their name prefixed by R_ useDynLib(stats, .registration = TRUE, .fixes = "R_") ). You say 'now': 'we' (R-core) never had loess_raw as an R symbol, rather "loess_raw" as a character string. -- Brian D.
