Hi all,

"smart" lost this round.

I always use explicit return(something) in my functions, when they are supposed to return a value regardless of whether it is a list, numeric, NULL or data frame some other thingy.

Yes, that involves tapping a few times more on the keyboard but it does solve a lot of problems and best of all, it makes code readable.

In language like C you would never run into this phenomenon. You declare explicitly which type the function returns and you will be bombarded with errors or warnings if you fail to return the right type of if you forget the return statement. I find it very comfortable.

I could be wrong, but...

Best regards,
ElMaestro

R's base package has 274 reserved words and operators, along with 1761 functions. I can use 18 of them (about 14 of them properly). I believe this makes me the Donald Trump of programming.
