[R-meta] Question on Fisher's z possible range of values

[Gabriel Cotlier]

Dear Michael,
Thank you very much for your reply and the information.
I think that knowing that z can take any value in the real line is
enough for my purpose, which is to report the range of values that z can
take.
Since I am transforming from r-tozm, I thought about giving a range of z to
guide readers.
Thank you very much again.
Gabriel
