rmonad (version 0.7.0)

A Monadic Pipeline System

Description

A monadic solution to pipeline analysis. All operations -- and the errors, warnings and messages they emit -- are merged into a directed graph. Infix binary operators mediate when values are stored, how exceptions are handled, and where pipelines branch and merge. The resulting structure may be queried for debugging or report generation. 'rmonad' complements, rather than competes with, non-monadic pipeline packages like 'magrittr' or 'pipeR'. This work is funded by the NSF (award number 1546858).
