Stan/RStan Installation Error

Interfaces RStan

Dear all,

After I followed all instruction at Home · stan-dev/rstan Wiki · GitHub and run the following codes,

fx ← inline::cxxfunction( signature(x = “integer”, y = “numeric” ) , ’

  • return ScalarReal( INTEGER(x)[0] * REAL(y)[0] ) ;
  •                        ' )

I got the following error message. Any help is appreciated.

Dear Bob,

Thanks for your instruction. But can you tell me how to remove? Thanks a lot!

Open that file in a text editor, put the cursor to the right of the offending part of CXXFLAGS and press the backspace key on Windows until the offending part is gone. Then save the file.

On a Mac, put the cursor to the left of the offending part of CXXFLAGS and press the delete key until the offending part is gone. Then save the file.

Bob,

Thanks a lot! Actually your first reply gave very clear instruction. Now, I’ve cleaned that markvar file, and got that expected reuturn, 10. Thanks a lot!
