## Testing
To test the R builds locally, you can build the images:
```bash
# Build images for all platforms
make docker-build
# Or build the image for a single platform
(cd builder && docker-compose build ubuntu-2004)
```
Then run the build script:
```bash
# Build R for all platforms
R_VERSION=4.0.5 make docker-build-r
# Build R for a single platform
(cd builder && R_VERSION=4.0.5 docker-compose up ubuntu-2004)
# Alternatively, run the build script from within a container
docker run -it --rm --entrypoint "/bin/bash" r-builds:ubuntu-2004
# Build R 4.0.5
R_VERSION=4.0.5 ./build.sh
# Build R devel
R_VERSION=devel ./build.sh
# Build a prerelease version of R (e.g., alpha or beta)
R_VERSION=rc R_TARBALL_URL=https://cran.r-project.org/src/base-prerelease/R-latest.tar.gz ./build.sh
```
