# Solved:How to calculate first difference between values in the same column.

I found RapidMiner pays more attention on columns(of course in the data mining), however, sometimes we need calculation in the rows not only in in columns . I know there is a Finance and Economics package ,but its differencing method only provides the return or growth rate of values , i.e. (Pt+1- Pt)/Pt, not the first difference which can be got by "Pt+1 - Pt". Are there some ways to get that?

I like RapidMiner! I enjoy the work with it.

Thanks.
