Change default browser in shiny R

Question

I am using "01_hello" in RStudio and while it won't show the histogram when the program opens by default in IE, even in Chrome, the slider bar does not work. I cannot slide the bar and see the change in the histogram.

How can I change the default browser in R so that the shiny launches Chrome and not IE.?

On the main site this issue has been asked in the comments, the moderators have said that it will open your machine's default browser -- it does not rely on R env variables.
