RTutor * Home * Data * Report * EDA * Ask * About CHAT WITH YOUR DATA VIA AI STILL BEING TESTED AND IMPROVED. LOADING ... ... Reset Submit Settings Help improve RTutor How useful is RTutor? Not at all Slightly Helpful Extremely Your experience with R: None Beginner Intermediate Advanced Save Feedback HI I'M YOUR STATISTICS TUTOR. I AM STILL IN COLLEGE LEARNING NEW THINGS. BUT I TRY TO BE HELPFUL. I DID FINISH MY REQUIRED READING: THOUSANDS OF BOOKS, MILLIONS OF CODE REPOSITORIES, AND BILLIONS OF WEB PAGES OF ALL KINDS. I'M NOT BEING HYPERBOLIC. JUST BRAGGING. BTW, I ALSO LEARNED A FEW DOZEN FOREGIN LANGUAGES. -------------------------------------------------------------------------------- TIPS: * Start small. Gradually add complexity. First, try simple requests such as distributions, basic plots, or simple models. Then customize it or add variables. * Released as a prototype for testing, RTutor was just an idea 25 days ago. Keep your expectations low and send us your valuable feedback (lower left). * It can take a few tries to get it correct. If it still does not work, rephrase your request. Also, increase the "Temperature" setting will make the AI more aggressive in seeking alternative solutions. * Prepare and clean your data in Excel first! RTutor can only analyze traditional statistics data, where rows are observations and columns are variables. * Once uploaded, your data is automatically loaded into RTutor as a data frame called df. * Check if the data types are correct: numeric columns vs. categories (factors or characters). See below. You can tell RTutor to convert by saying "Convert cyl as numeric", or "Convert year as factor". We try to auto-detect (Settings). Data types make a big difference in analysis and plots! * Before sending your request to OpenAI, we add "Generate R code" before it, and append something like "Use the df data frame. Note that hwy is numeric" afterward. If you are not using any data (plot a function or simulations), choose "No data" from the Data dropdown. * Your data is not sent to the AI. To ask generic questions without mentioning column names, briefly describe your data, especially the relevant columns, just like emailing a statistician who knows nothing about your data. * Each chunk of code is run independently using your uploaded data. If you want to build upon the current code, select the "Continue from this chunk" checkbox. Your current R code will be inserted before your next chunk and get executed. This is especially important for data wrangling when you remove rows, add columns, or log-transform. You can go back to any previous chunks and continue from there. -------------------------------------------------------------------------------- AI generated code: Continue from this chunk RESULTS: -------------------------------------------------------------------------------- Code chunks to include: RMarkdown * Basic * Summary * Table1 * Categorical * Numerical * Correlation * GGpairs GENERATED BY THE SUMMARYTOOLS PACKAGE USING THE COMMAND:SUMMARYTOOLS::DFSUMMARY(DF).

Example questions: Example questions: Ask RTutor -------------------------------------------------------------------------------- RTutor uses OpenAI's powerful text-davinci-003 language model to translate natural language into R code, which is then excuted. You can request your analysis, just like asking a real person. Upload a data file (CSV, TSV/tab-delimited text files, and Excel) and just analyze it in plain English. Your results can be downloaded as an HTML report in minutes! NO WARRANTY! Some of the scripts run but yield incorrect result. Please use the auto-generated code as a starting point for further refinement and validation. The RTutor.ai website and the source code (CC BY-NC 3.0 license) are freely availble for academic and non-profit organizations only. Commercial use beyond testing please contact gexijin@gmail.com. -------------------------------------------------------------------------------- Personal project by Steven Ge. For feedback, please email gexijin@gmail.com.

WHAT IS RTUTOR? It is an artificial intelligence (AI)-based app that enables users to interact with your data via natural language. After uploading a dataset, users ask questions about or request analyses in English. The app generates and runs R code to answer that question with plots and numeric results. 2. HOW DOES RTUTOR WORK? The requests are structured and sent to OpenAI’s AI system, which returns R code. The R code is cleaned up and executed in a Shiny environment, showing results or error messages. Multiple requests are logged to produce an R Markdown file, which can be knitted into an HTML report. This enables record keeping and reproducibility. 3. CAN PEOPLE WITHOUT R CODING EXPERIENCE USE RTUTOR FOR STATISTICAL ANALYSIS? Not entirely. This is because the generated code can be wrong. However, it could be used to quickly conduct data visualization, and exploratory data analysis (EDA). Just be mindful of this experimental technology. 4. WHO IS IT FOR? The primary goal is to help people with some R experience to learn R or be more productive. RTutor can be used to quickly speed up the coding process using R. It gives you a draft code to test and refine. Be wary of bugs and errors. 5. HOW DO YOU MAKE SURE THE RESULTS ARE CORRECT? Try to word your question differently. And try the same request several time. A higher temperature parameter will give diverse choices. Then users can double-check to see if you get the same results from different runs. 6. CAN YOU USE RTUTOR TO DO R CODING HOMEWORK? No. That will defy the purpose. You need to learn R coding properly to be able to tell if the generated R coding is correct. 7. CAN PRIVATE COMPANIES USE RTUTOR? No. It can be tried as a demo. RTutor website dnd source code are freely available for non-profit organizations only and distributed using the CC NC 3.0 license. 8. CAN YOU RUN RTUTOR LOCALLY? Yes. Download the R package and install it locally. Then you need to obtain an API key from OpenAI. 9. WHY DO I GET DIFFERENT RESULTS WITH THE SAME REQUEST? OpenAI’s language model has a certain degree of randomness that could be adjusted by parameters called "temperature". Set this in Settings 10. HOW MUCH DOES THE OPENAI’S COST PER SESSION? About $0.01 to $0.1, if you send 10 to 50 requests. We have a monthly usage limit. Once that is exceeded, the website will not work for the month. If you use it regularly, please use your API key. Currently, RTutor receives no funding. We might ask users to contribute later. 11. CAN THIS REPLACE STATISTICIANS OR DATA SCIENTISTS? No. But RTutor can make them more efficient. 12. HOW DO I WRITE MY REQUEST EFFECTIVELY? Imagine you have a summer intern, a collge student who took one semester of statistics and R. You send the intern emails with instructions and he/she sends back code and results. The intern is not experienced, thus error-prone, but is hard working. Thanks to AI, this intern is lightning fast and nearly free. 13. CAN I INSTALL R PACKAGE IN THE AI GENERATED CODE? No. But we are working to pre-install all the R packages on the server! Right now we finished the top 5000 most frequently used R packages. Chances are that your favorite package is already installed. 14. CAN I UPLOAD BIG FILES TO THE SITE? Not if it is more than 10MB. Try to get a small portion of your data. Upload it to the site to get the code, which can be run locally on your laptop. Alternatively, download RTutor R package, and use it from your own computer. 15. THE SERVER IS BUSY. OR THE WEBSITE IS STUCK! Start a new browser window, not another tab. You will be assigned to a new worker process. You can also try our mirror site https://bcloud.org. 16. VOICE INPUT DOES NOT WORK! One of the main reason is that your browser block the website site from accessing the microphone. Make sure you access the site using https://RTutor.ai. With http, mic access is automatically blocked in Chrome. Speak closer to the mic. Make sure there is only one browser tab using the mic. --------------------------------------------------------------------------------
