Thanks Duncan. I had the feeling I was doing something wrong but did not realise it was that stupid.
showNonASCII('ggplot(df, aes(x = x)) + geom_histogram(aes(y = ..density..)), binwidth = 1, colour = "black", fill = "white")') now runs and does what the help page seems to imply: Nothing. >From the showNonASCII help page: "The elements of x containing non-ASCII characters will be returned invisibly. " One gets a result one does not see? Does one have to explicitly capture the result somehow? I really have not the faintest idea of what the example from the help page is doing.
