| **Transformation** | **Description** |
|------------------|-----------------|
|------------------|--------------------|
| [Define](classROOT_1_1RDF_1_1RInterface.html#a7d48eb23b4378e99ebccb35e94ad025a) | Creates a new column in the dataset. |
| [DefineSlot](classROOT_1_1RDF_1_1RInterface.html#acaacf727b8a41d27c6bb4513348ac892) | Same as `Define`, but the user-defined function must take an extra `unsigned int slot` as its first parameter. `slot` will take a different value, `0` to `nThreads - 1`, for each thread of execution. This is meant as a helper in writing thread-safe `Define` transformation when using `RDataFrame` after `ROOT::EnableImplicitMT()`. `DefineSlot` works just as well with single-thread execution: in that case `slot` will always be `0`. |
| [DefineSlotEntry](classROOT_1_1RDF_1_1RInterface.html#a4f17074d5771916e3df18f8458186de7) | Same as `DefineSlot`, but the entry number is passed in addition to the slot number. This is meant as a helper in case some dependency on the entry number needs to be honoured. |
