I am currently trying to run the demo/examples as per your rinterface website and I encounter the following error with dashboardPage.

Okay, so I see this is because R is trying to use the dashboardPage and dashboardHeader functions from the shinydashboard package and not shinydashboardPlus.

If I define the following -

dashboardHeader <- shinydashboardPlus::dashboardHeader
dashboardPage <- shinydashboardPlus::dashboardPage

then run the example, it works.

What is the best way to avoid this scenario in general when you have the same function names in different packages?

[lmsimp]

Again, answering the above. I see I need to explicitly load shinydashboard and then shinydashboardPlus to ensure the order of loading is correct and functions are not masked.

Specifically,

library(shinydashboard)
library(shinydashboardPlus)
shinydashboardPlusGallery()
