This video demonstrates how to use RStudio and the rSysrev (rsr) package to programmatically label articles with external data by using the rsr::review() command: https://r.sysrev.com/reference/review...
In this video, we use the review() command to push meta-data, specifically Publication Year, in the form of categorical labels which can then be used as to filter the articles.
