You can use `pixi` to manage your R dependencies. The conda-forge channel contains a wide range of R packages that can be installed using `pixi`.
## Installing R packages
R packages are usually prefixed with `r-` in the conda-forge channel. To install an R package, you can use the following command:
```bash
pixi add r-<package-name>
# for example
pixi add r-ggplot2
```
## Using R packages in RStudio
To use the R packages installed by `pixi` in RStudio, you need to run `rstudio` from an activated environment. This can be achieved by running RStudio from `pixi shell` or from a task in the `pixi.toml` file.
## Full example
The full example can be found here: [RStudio example](https://github.com/prefix-dev/pixi/tree/main/examples/r).
Here is an example of a `pixi.toml` file that sets up an RStudio task:
```toml
[workspace]
name = "r"
channels = ["conda-forge"]
platforms = ["linux-64", "osx-64", "osx-arm64"]
[target.linux.tasks]
rstudio = "rstudio"
[target.osx.tasks]
rstudio = "open -a rstudio"
# or alternatively with the full path:
# rstudio = "/Applications/RStudio.app/Contents/MacOS/RStudio"
[dependencies]
r = ">=4.3,<5"
r-ggplot2 = ">=3.5.0,<3.6"
```
Once RStudio has loaded, you can execute the following R code that uses the `ggplot2` package:
```R
# Load the ggplot2 package
library(ggplot2)
# Load the built-in 'mtcars' dataset
data <- mtcars
# Create a scatterplot of 'mpg' vs 'wt'
ggplot(data, aes(x = wt, y = mpg)) +
geom_point() +
labs(x = "Weight (1000 lbs)", y = "Miles per Gallon") +
ggtitle("Fuel Efficiency vs. Weight")
```
!!! Note
This example assumes that you have installed RStudio system-wide.
We are working on updating RStudio as well as the R interpreter builds on Windows for maximum compatibility with `pixi`.
