As an R developer, I can deeply relate to this. People that use R as the mother language are probably from academia. They can be very good at data analysis and scripting, but usually have no idea of software development. They have few knowledge about versioning, modularization, documentation, and testing, which can lead to issues when they develop production-level R packages and Shiny applications.
On the flip side, R developers with strong software development skills can be incredibly valuable in academic settings.
