There are some tutorials online.
https://cran.r-project.org/web/packages/flowr/vignettes/flowr_overview.html
https://github.com/flow-r/flowr
https://www.rdocumentation.org/packages/flowr/versions/0.9.11
https://flowr.readthedocs.io/en/latest/rd/vignettes/build-pipes.html
Can you get the examples in the tutorials to work?
Regards,
Tim
