It sure would be handy if the Lag Column node output the lagged column name as a flow variable!
Hi @MrSampson and welcome back to the KNIME forum,
It is already possible to do that in the “Flow Variables” tab of the node’s configuration window:
Thanks @armingrudd. I’m sorry I was unclear. I mean the output column, like the one with the column name as “lag-column(-1)”.
It is easy to create it having the original column name. If the original column name is provided by the variable “lag-column” you can use the String Manipulation (Variable) node to create the column name:
Right. And I can use the flow variable for the lag to fill out the column name, so I wouldn’t have to change it manually every time I change the lag. That’s why I suggested it would be “handy” by saving me the couple of mintues of doing that.
It’s no big deal, I just thought I would throw it out there. (Including an input field to change the output column name, would also be nice.)
if you are after to rename lagged column maybe this topic helps:
