Session Interaction

The rstudioapi package allows you to interact with the running R session in a couple useful ways: you can send code to the R console, or restart the R session.

Running at Startup

Typically, code that you want to run at the start of an R session is placed into an .Rprofile file (see Initialization at the Start of a Session for details). However, RStudio’s API hooks are not available until RStudio has fully started up, so most rstudioapi methods will not work inside .Rprofile.

If you want to invoke rstudioapi methods on session startup, use the rstudio.sessionInit hook. For example, to print the RStudio version to the R console when the session begins:

setHook("rstudio.sessionInit", function(newSession) {
  if (newSession)
    message("Welcome to RStudio ", rstudioapi::getVersion())
}, action = "append")
