Invalid registration code for packages with dot in name

[krlmlr]

Example: ropensci-archive/tic.drat@1370bec#diff-cccf79352b3795dd56362ef855dd939bR23

The generated code reads (comments mine):

static const R_CallMethodDef CallEntries[] = {
    {"tic.drat_divide", (DL_FUNC) &tic.drat_divide, 2}, // remove this
    {"tic_drat_divide", (DL_FUNC) &tic_drat_divide, 2},
    {NULL, NULL, 0}
};

RcppExport void R_init_tic.drat(DllInfo *dll) { // use underscore instead of dot
    R_registerRoutines(dll, NULL, CallEntries, NULL, NULL);
    R_useDynamicSymbols(dll, FALSE);
}

The exported function can be called when I register manually (but compileAttributes() still insists on adding its own code): ropensci-archive/tic.drat@7b0bdb3

This is with the latest Rcpp 5ca4f6a.

Good catch! I think we need to substitute underscore for dot as you said. I'll fix this ASAP.

Thanks @jjallaire for the quick fix! Works as advertised: ropensci-archive/tic.drat@aff657e.
