To establish the unified style and initial code for all .R files, press Ctrl+Alt+S to open project Settings, go to Editor | File and Code Templates, select R Script in the list of languages, and alter the default template. In the following example, we modified the default settings and added the ${TIME} variable to include the time when the file was created.

To preview the R constructs, press Ctrl+Alt+S to open project Settings, go to Editor | Live Templates, select R Script in the list of languages

When you work with R plugin in DataSpell, all scope of your R data is considered an R workspace.

  • Select Load workspace on R startup to ensure all your R content becomes available when you start DataSpell with the R plugin.
