Question 1

What is an online R compiler?

Accepted Answer

An online R compiler lets you write, run, and debug R code directly in your browser — no downloads, no setup. RChat uses WebR (R compiled to WebAssembly) so your R code executes entirely client-side with near-native performance.

Question 2

Can I use R packages like ggplot2 and dplyr?

Accepted Answer

Yes. RChat automatically detects library() and require() calls in your code and installs missing packages on the fly via the WebR package repository. Popular packages like ggplot2, dplyr, tidyr, and lubridate are all supported.

Question 3

Is it free to use?

Accepted Answer

Yes — you can start running R code for free. Create a free account to unlock persistent project storage, dataset uploads (up to 10 MB), AI-powered code generation, and more. No credit card required.

Question 4

Do I need to install anything?

Accepted Answer

No. RChat runs entirely in your browser. There is nothing to download or configure — just open the page and start writing R code.
