[R] NAs introduced when changing data type

[Tord Snall]

Hi all,
I am trying to change data type in the Data Editor but when I do, all
numbers in the column changes to NA and back in the Console I get the
warning message "NAs introduced by coercion".

What's wrong? The table consists of 95 columns and 470 rows.
