Date to Nominal Function

rowan_g

Hi,

Not sure if this has been requested. A Date-to-Nominal function for use in the Generate Attributes operator would be awesome!

Thanks for all the great work! Rapidminer is a fine piece of software! Keep it up1

Sorry - didn't realise date parse custom was the operator to use.

Thanks!
