1 Introduction

In academic research, particularly in statistics, biostatistics, and social sciences, R is the undisputed leader. While Python has gained popularity in machine learning and computer science, R continues to dominate in traditional statistical research and peer-reviewed publications.

2 R’s Academic Foundation

2.1 Built by Statisticians, for Statisticians

R was created by Ross Ihaka and Robert Gentleman at the University of Auckland, New Zealand, specifically for statistical computing. This academic origin has shaped R’s development and adoption in research communities worldwide.

2.2 Statistical Society Endorsements

Major statistical societies and journals recognize R’s importance:

American Statistical Association (ASA): Official R support and workshops
Royal Statistical Society (RSS): R-focused conferences and publications
Journal of Statistical Software: Many R packages are peer-reviewed
Biometrics: Standard tool for biostatistical research

3 Peer-Reviewed Packages

3.1 CRAN’s Quality Control

R’s Comprehensive R Archive Network (CRAN) hosts over 18,000 packages, many of which are peer-reviewed:

Code

# Examples of peer-reviewed R packages
peer_reviewed_packages <- c(
  "lme4",      # Mixed effects models
  "survival",  # Survival analysis
  "nlme",      # Nonlinear mixed effects
  "mgcv",      # Generalized additive models
  "brms",      # Bayesian regression
  "rstan"      # Stan integration
)

# These packages are published in statistical journals
# and undergo rigorous peer review

3.2 Publication in Statistical Journals

Many R packages are published in prestigious statistical journals:

Journal of Statistical Software: Dedicated to R package publications
R Journal: Official R Foundation journal
Computational Statistics: R-focused research
Biostatistics: R packages for medical research
