Thank you.
I reported an "enhancement" #18409 at https://bugs.r-project.org/show_bug.cgi?id=18409
I took in account your suggestions to improve error messages.

I choosed to provide different messages for character and logical/numeric indices, but this increases the code size, the number of code paths and the number of translations to perform.
If you have suggestions to improve the patch, I am open to comments and ideas.
