Is R suitable for production pipelines?

Yes, with APIs (plumber), containers, and CI/CD. For scale, integrate with Sparklyr or database-backed workflows.

Category: Opinion

What is the biggest misunderstanding about R?

That it’s only for academics. R is widely used in finance, pharma, and marketing with robust industry-grade tooling.

Category: Misunderstanding

Where should beginners learn R?

Start with R for Data Science and Tidyverse tutorials. Practice with datasets in RStudio and R Markdown.

Category: Learning

What are typical R pitfalls?

Package version drift and inconsistent environments. Use renv and lockfiles to ensure reproducibility.

Category: Mistakes

How does R integrate with databases?

DBI interfaces and dbplyr enable SQL translation and pushdown. Use arrow for columnar data exchange.
