How to view function description without help?

Recently, when using vscode, I found that there is a function of 'Extended documentation on hover' in Language Service(A larger preview of the documentation is shown when users mouse over R symbols). Is there a similar method to achieve this in RStudio?

like this ?

I'm not aware of having done anything to have this; I think its out of the box behaviour.

yes,just like this

ok great, glad I could help
