WebSep 20, 2024 · RDataFrame is ROOT’s high-level interface for data analysis since ROOT v6.14. By now many real world analyses use it, and on top of that we see lots of non-analysis usage in the wild. Parallelism has always been a staple of its design with support for executing the event loop on all cores of a machine thanks to implicit multi-threading. 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. RDataFrame is built with a modular and flexible workflow in mind, summarised as follows: build a data-frame object by specifying your data-set
