The Problem (Q-score 7, ranked #69th of 95 in the VBA Core archive)
The scenario as originally posted in 2013
I have to manage a workflow involving R-scripts and VBA-code.
I would like to run the process in R (where most of my code is) and now and then to call VBA-code for specific calculation. I would prepare the inputs for VBA in R, write somewhere the results (.csv, database) and then use the results in the rest of the R-script.
The best would be of course to move the whole code into R but this is for now not possible. The VBA-code is fairly complex. Translating this into R will be a challenging long-term task.
Is there any possibility to manage in R such a work-flow?

What changed between 2013 and 2026
The answer is 13 years old. The VBA Core object model has been stable across Office 2013, 2016, 2019, 2021, 365, and 2024/2026 LTSC, so the pattern still compiles. Changes that might affect you: 64-bit API declarations (use PtrSafe), blocked macros in downloaded files (Mark-of-the-Web), and the shift toward Office Scripts for web-first workflows.
