rstudioapi::restartSession() does not clear environment or search in R3.4.4

[vnijs]

It seems that since R 3.4.4 rstudioapi::restartSession() backs-up (and restores) the current environment and doesn't unload packages. Session > Restart R from the menu does still work as expected. Does Rstudio call a different function? Is there an option to have rstudioapi::restartSession() behave the same as the menu?

FYI settings:

FYI Same issue in R 3.5

Thanks for the bug report! I've copied this over to the RStudio repository as we'll need some changes there to support this.

This still seems to be unresolved. Is there any intention to offer a genuine session refresh?

Restarting R session...

Sorry for taking so long to respond.

I think rstudioapi::executeCommand("restartR") should do what you need -- it invokes the same command as the Session -> Restart R would as invoked from the menu.

[vnijs]

Thanks @kevinushey! Question: Is it possible to have R(studio) run a user provided command after restart? Like rstudioapi::restartSession(cmd)

[kevinushey]

Unfortunately no, not via that interface.

[vnijs]

@kevinushey Should create a new feature request for the combined functionality of rstudioapi::executeCommand("restartR") and rstudioapi::restartSession(cmd)?

[kevinushey]

I think we just need some way to configure restartSession() to behave like the "regular" restart session command.

[vnijs]

If restartSession could have the option (or default) to behave like rstudioapi::executeCommand("restartR") but with the option to run commands after running that would be fantastic!

I've filed rstudio/rstudio#11378 for us to follow up this extension on the RStudio side.
