[Rcpp-devel] Are there any C++ function name restrictions?

It works fine here:

edd at don:/tmp/foobar$ rm src/*.o src/*.so
edd at don:/tmp/foobar$ grep Tables src/* R/*
src/rcpp_hello_world.cpp:RcppExport SEXP conditionalProbabilityTables(){
src/rcpp_hello_world.h:RcppExport SEXP conditionalProbabilityTables() ;
R/rcpp_hello_world.R:		  .Call( "conditionalProbabilityTables",
PACKAGE = "foobar" )
edd at don:/tmp/foobar$ R CMD INSTALL .

You really don't want to check in .o and .so files.  It may have been as
simple as you not recompiling before running install.  _Always_ clean, a
script like


   rm -f src/*.o src/*.so

may help.
