[Rcpp-devel] Are there any C++ function name restrictions?
Since you changed the function name, you can no longer call rcpp_hello_world() from R. Try calling the new function name. Better yet, start over, leave rcpp_hello_world code alone and add another .cpp, .h, and .R file with another function. Dale

Dear Dirk, Hadley and Rccp Experts, thank you very much for your input. Unfortunately I still cannot solve my problem. I took Dirk's advise and used Rcpp.package.skeleton(name="foobar") to create a new Hello-World package. Then I build and installed it with R CMD INSTALL foobar/ From an interactive R shell I could call the function rcpp_hello_world() successfully. Then the very only thing I did was changing the function name rcpp_hello_world to conditionalProbabilityTables in three files src/rcpp_hello_world.h, src/rcpp_hello_world.cpp, and R/rcpp_hello_world.R Finally I rebuild it with R CMD INSTALL foobar and could no longer call function rcpp_hello_world() in an interactive R shell.
rcpp_hello_world()
Error in .Call("conditionalProbabilityTables", PACKAGE = "foobar") :
"conditionalProbabilityTables" not available for .Call() for package "foobar"
I put the whole test project "foobar" to be browsed and checked out on github:
https://github.com/asishallab/foobar
Please help me resolve my issues.
Thank you very much.
