Online R Script Compiler

Run R scripts online: paste your R script, press Run, and it is executed with Rscript on R 4.5. Results printed with print() and cat() appear in the output panel as the script runs.

How to run R code online

  1. This page opens with R selected, so you can start typing straight away.
  2. Write your code in the editor, or open files from your computer: single files, or a whole project as a .zip.
  3. Press Run, or Ctrl+Enter. The output appears in the panel beside the editor, and when the program asks for input you type it there and press Enter.
  4. Share a copy with a link, or save your files to your computer.

R 4.5 (Rscript) on Online IDE

  • Scripts run with Rscript, the same way you would run them from a terminal.
  • Rscript is not interactive, so read input with readLines(file("stdin"), n = 1) instead of readline().
  • Results you print with print() or cat() appear in the output panel straight away.

Example: a R program that reads input

scores <- c(72, 85, 90, 64, 78)

cat("Mean:", mean(scores), "\n")
cat("Median:", median(scores), "\n")
cat("Highest:", max(scores), "\n")
print(summary(scores))

Frequently asked questions

Which R version does Online IDE run?

R 4.5, run with Rscript on Linux.

Why does readline() not wait for my input?

readline() only waits in an interactive R session, and Rscript is not interactive. Use readLines(file("stdin"), n = 1) to read a line you type in the output panel.

Is this the same as an online RScript compiler?

Yes. R is interpreted rather than compiled, and every script here runs with Rscript, so you get the same result as running Rscript main.r on your own computer.
