[Rd] length-0 list as dimnames

Hi,

I'm working on a package and observed a behaviour that was suggested to be incompatible with the documentation.

The code below:

x <- matrix(1:4, 2)
dimnames(x) <- list()

works just fine. But checking the documentation for dimnames(), it states that if value is a list "its components are either 'NULL' or a character vector with positive length of the appropriate dimension of x".

Should dimnames() return an error on the example above?

Thank you very much for your attention and time,

benilton
