What recruiters should know
R sits at 1.88% TIOBE (2026) vs Python at 22%+, but remains the gold standard for biostatistics, clinical trials, and statistical research. R appears in 33% of data scientist job postings. The FDA accepts R-generated clinical trial tables without additional validation, making it irreplaceable in pharmaceuticals and healthcare research. For industry roles and AI/ML, Python is the stronger choice. R's niche is deep statistical analysis, academic research, and peer-reviewed scientific publishing — sectors that are stable and have high institutional inertia.
