I'm pretty sure that a lot of you guys out there are using git as CVS. How do you bypass the following warning on R CMD check:

* checking for executable files ... WARNING
Found the following executable file(s):

I tried by putting .git folder in .Rbuildignore, but with no luck.

I reckon that this one is trivial for all of you who are using Github to host R packages. Any ideas?

How do I find hidden .git files?

Use the terminal to display the . git directory with the command ls -a . The ls command lists the current directory contents and by default will not show hidden files. If you pass it the -a flag, it will display hidden files.

How do I view a .git folder?

The contents of the . git folder can be viewed using the tree command in a Windows Operating System. To switch from the git bash terminal to Windows terminal, type the cmd command. The user is presented with the Windows terminal now.

Yes, use .Rbuildignore and then build the .tar.gz and then check the .tar.gz and not the source directory.
