Dear Rusers, This summer I published the package rmonad on CRAN: https://cran.r-project.org/web/packages/rmonad rmonad is a toolset for building stateful, branching pipelines. As functions in the pipeline are executed, they are recorded in a graph of all past operations. The resulting structure can be computed on to access not only the final results, but also node documentation, intermediate results, performance stats, and any raised messages, warnings or errors. See the README on github (https://github.com/arendsee/rmonad) for a few motivating examples. For more detail, see the "introduction" vignette ( https://cran.r-project.org/web/packages/rmonad/vignettes/introduction.html ). Any thoughts, feature requests, or bug reports would be strongly appreciated. I am also looking for collaborators (see the last section of the github README).
