Checking for repeating ID?
Contributor II
Hi Guys,
Sometimes I create an ID attribute from part numbers x,y locations etc and if there is ever a repeating sample in my large data set it would be nice to see. I am surprised that RM lets the ID attribute contain repeating values.
What is the quickest way to check if there are any repeating values (not necessarily nominal) for a particular attribute?
It would be cool if there was a meta data column for that.

in fact there is a meta data value for this: Take a look at the mode, this is the most frequent nominal value. If this value occurs just once, then each value is unique.

Will mode only be computed for nominal attributes?
Thanks,

that's true: Mode is only calculated for nominal data. You could use Numerical to Polynomial to convert it.
