Is your feature request related to a problem? Please describe. In order to install the latest push to VSCode-R, users have to manually download and install the extension artefact from the github repo.

Describe the solution you'd like Have a pre-release version of the extension available for installation through the extension marketplace.

Pre-releases can be made through the CLI: vsce publish --pre-release
