[R] Convert NA to '.'

[David_D]

Jorge,

Thanks a lot for your reply. It's indeed working in this case. However, with
data frames mixing numeric and character is not working anymore. Morever I
am working with many variables and I don't want to modify them. What I would
really appreciate is a global option (in the Rprofile?) that allow to change
the display nd printing of NA by any symbol?

Does it exist?

Best regards,
David
