Hi We (me and Brendan) has been focusing on other things like journeys apart from new MLCtx changes. R4ML commits and PR you can also review, I think code will definitely be maintained.

For some perspective, SystemML has 1013 commits in the last year (~2.78 per day). No R4ML commits in 2 months is concerning for obvious reasons. It implies no real work has been done on the project for months. > * Providing wrappers for our algorithm scripts would be just a start > because it hides our core value proposition of custom large-scale ML. > Hence, we would also need an MLContext equivalent that allows to execute > arbitrary DML scripts or R functions.

Looking over the code at https://github.com/SparkTC/r4ml/blob/master/R4ML/R/sysml.bridge.R, it looks https://avatars2.githubusercontent.com/u/13631156?v=4&s=400 SparkTC/r4ml github.com r4ml - Scalable R for Machine Learning like the code in the R4ML master branch utilizes an old API that does not currently exist in SystemML. As Matthias pointed out, a key value proposition of SystemML is customizable machine learning, which would require an API that currently exists in the project. That said, I believe an R API interface to SystemML is extremely valuable and I think the whole SystemML community would benefit from the R API, and I hope you will pursue the issue further. It looks like it has been in development since June (https://github.com/SparkTC/r4ml/pull/50). https://avatars2.githubusercontent.com/u/12959246?v=4&s=400 [WIP][I-50][R4ML-123] new MLContext API by aloknsingh · Pull Request #50 · SparkTC/r4ml github.com Developer's Certificate of Origin 1.1 By making a contribution to this project, I certify that: (a) The contribution was created in whole or in part by me and I have the right to subm...
