RTutor

RTutor is a web application that turns plain English requests into R code for data analysis. A user loads a dataset by uploading a file or choosing one of many built in demo datasets, checks the detected data types, and types a request such as a distribution, a basic plot or a summary. RTutor generates the R code, runs it, and shows the results, and a Show Code option exposes the generated script. An Ask About Results feature lets users put follow up questions about the output. Within a session, earlier questions and code chunks are kept as context, so a new request can build on previous results. An exploratory data analysis tab produces summaries, tables, correlation plots and pair plots using standard R packages such as DataExplorer, summarytools, tableone, corrplot and GGally, and a report can be exported as RMarkdown. The source code is on GitHub, along with instructions for installing RTutor as an R package. The tool is aimed at researchers, students and analysts who work with data but do not want to write R by hand. The site describes the project as coming from a small startup that is open to partnerships with academia and industry, and points users to a related platform, Datably.ai, for multiple file formats and Python support. The default model is an OpenAI model. The site's setup instructions describe adding an OpenAI API key with a usage limit, noting that $5 per month is more than enough. No separate pricing page is published.
