Test if an object is plotly

this may be a fairly straight forward question.

I am wanting to test if an object is a plotly object or not. I would ideally be testing a ggplotly() object.

Is there any simple way to do this? I can't seem to find a function like;

> x <- ggplot()
> 
> is.ggplot(x)
[1] TRUE

If anyone could point me in the right dirction that would be greatly appreciated!

Solution 
  • class(x)

    returns

    [1] "plotly"     "htmlwidget"

    where x is created using ggplotly.

    So how about something like:

    "plotly" %in% class(x)
[1] TRUE

    You could make it into a function is.plotly:

    is.plotly <- function(x) {
  "plotly" %in% class(x)
}
