R: error with generating png images: figure margins too large

[barracuda156]

Any idea how to fix this? Recurring error with a number of ports.

Example:

* checking examples ... ERROR
Running examples in ‘shinylight-Ex.R’ failed
The error most likely occurred in:

> ### Name: encodePlot
> ### Title: Renders a plot as a base64-encoded image
> ### Aliases: encodePlot
> 
> ### ** Examples
> 
> pdf <- encodePlot(grDevices::png, "image/png", 200, 300, function() {
+   barplot(c(1, 2, 3, 4))
+ })
Error in plot.new() : figure margins too large
Calls: encodePlot -> plotFn -> barplot -> barplot.default -> plot.new
Execution halted
