Thanks!

I agree that DESCRIPTION should be updated. However, maybe we should not put your information into the skeleton Rmd so that your information are not left in all template document created and we do not have to update them while they change.

Don't you think ?

[jooyoungseo]

Agreed, @cderv! I will update the default skeleton author info following the original template by tomorrow.

Thanks !
