 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
