Dear Seth

Thank you for this tip, I just tried it and here is the result:

Welcome to MyClass
 > writeFileCpp("myout_fileCpp.txt")
[1] "outfile =  myout_fileCpp.txt"
Writing file myout_fileCpp.txt using C++ style.

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x00000006
0x020fe231 in std::ostream::flush (this=0x214f178) at 
No such file or directory.

It seems that it cannot find ostream.tcc, whatever this extension means.

Best regards
