RStudio

For Rstudio we recommend using the 'Local Jobs' feature to run jobs in the background. This way you can submit multiple jobs whilst also making sure the job continues to run if you navigate away from Rstudio without blocking the interface.

Recovering an unresponsive RStudio session

In certain cases RStudio sessions can become unresponsive, due to large amounts of output printed or large amount of data loaded. If restarting the application in Nuvolos doesn't resolve the issue, you can follow the steps in the Application Troubleshooting guide to clear the application state.

RStudio is responsive but it doesn't accept commands

If you can interact with the RStudio window (menu items are working, dropdowns open, etc.) but commands you try to run in R will not execute, it might be that the R console is showing a plus sign at the start of the line:

R waiting for further input

If this is the case, R is waiting for further input. As you can see in the above example, a curly brace was open, and R waits the curly brace to be closed for the expression to be complete (and executable).

If you want to cancel the statement, make sure to focus on the R console in RStudio by clicking on it, then hit the Escape button on your keyboard.

After the cancelled statement

Using Tensorflow and Keras with RStudio

Tensorflow and Keras can be installed via miniconda in Rstudio. To install them, use the following steps:

1. Restart the R session to be in a clean setting (select Session > Quit Session on the top menu)

2. Make sure reticulate can use miniconda via running in the R commands:

Sys.setenv("RETICULATE_MINICONDA_ENABLED" = TRUE)
reticulate::install_miniconda()

3. Install tensorflow R package and then call the install_tensorflow() function. If you would like to use GPU acceleration, run install_tensorflow(version="gpu"):

install.packages("tensorflow") 
library(tensorflow)
install_tensorflow() # use install_tensorflow(version = "gpu") for GPU support

4. Install Keras R package and then call the install_keras() function:

install.packages("keras")
library(keras)
install_keras()

To test the installation, follow the example from the RStudio website: https://tensorflow.rstudio.com/guide/keras/#mnist-example

GitHub Copilot with RStudio

Starting from RStudio app version R 4.3.2 with RStudio 2023.09, the GitHub Copilot integration is configurable in Global Options:

GitHub Copilot requires a GitHub account with an active GitHub Copilot subscription. It currently cannot make use of an OpenAI API key. For OpenAI API integration, see the ellmer package section below.

Using ellmer with OpenAI GPT-5.2 and other Large Language Models

The ellmer package provides a unified interface for interacting with large language models directly from R, including OpenAI's GPT-5.2. This allows you to leverage AI capabilities for code generation, data analysis assistance, and natural language processing tasks within your RStudio workflow.

Installation

Install the ellmer package from CRAN:

install.packages("ellmer")
library(ellmer)

Configuration with OpenAI API

To use ellmer with OpenAI's GPT-5.2 model, you need to provide your API key.

You need an OpenAI API key from a paid OpenAI API account. A ChatGPT subscription is not sufficient - you must create an API key at platform.openai.com/api-keys.

We recommend storing your OpenAI API key as a Nuvolos secret, which will be automatically exposed as an environment variable in your application. See Environment Variables and Secrets for details on how to set up secrets.

Set up your OPENAI_API_KEY as a Nuvolos secret. Once configured, the secret will be available as an environment variable when your RStudio application starts, and ellmer will automatically detect it.

Using ellmer with GPT-5.2

Create a chat object to interact with the GPT-5.2 model:

library(ellmer)

# Set OpenAI API key from Nuvolos secret
Sys.setenv(OPENAI_API_KEY = readLines("/secrets/OPENAI_API_KEY", warn = FALSE))

# Create a chat instance with GPT-5.2
chat <- chat_openai(model = "gpt-5.2")

# Send a message and get a response
chat$chat("How do I create a scatter plot with ggplot2?")

# Continue the conversation with context
chat$chat("Can you add a regression line to that plot?")

You can also use ellmer for more advanced tasks:

# Generate code completions
chat$chat("Write a function that calculates the mean of a numeric vector, handling NA values")

# Get help with data analysis
chat$chat("I have a dataframe with columns 'age', 'income', and 'education'. 
          What statistical tests should I use to analyze relationships?")

# Use streaming for longer responses
chat <- chat_openai(model = "gpt-5.2", stream = TRUE)
chat$chat("Explain the differences between linear and logistic regression")

Additional Configuration

You can customize the model's behavior with additional parameters:

# Configure temperature, max tokens, and other parameters
chat <- chat_openai(
  model = "gpt-5.2",
  temperature = 0.7,
  max_tokens = 2000,
  system_prompt = "You are an expert R programmer and statistician."
)
