Use withr::local_par to set graphical parameters

[weiyaw]

Hi,

Would you consider using withr::local_par to set the graphical parameters?

The current code sets the graphical windows to par(mfrow = c(1, 1)) at the end of functions. However, this line of code won't be executed if the functions exit prematurely. It also forcibly set the user's graphical windows to c(1, 1) which might not be desirable.

withr::local_par will only set the parameters in the local scope and revert the parameters back to its original state whenever functions stop running.

Weiyaw,

That's a great suggestion.

Our team will work on this.

Thank you,
Filipe
