Webthe ﬂexibility of RDataFrame and its ability to read data formats other than ROOT’s are characterised, as an example it is discussed how RDataFrame can directly read and analyse LHCb’s raw data format MDF. 1 Introduction The ROOT project is committed to take physicists from data acquisition to publication as eﬀectively as possible. WebRDataFrame provides methods to perform most common operations required by ROOT analyses; at the same time, users can just as easily specify custom code that will be executed in the event loop.
