Error in.External2 (C_dataviewer, x, title): unable to start data viewer

When I "Knit" a Markdown report in RStudio.Cloud, I repeatedly receive the following error:

> View(w) Error in .External2(C_dataviewer, x, title) : unable to start data viewer In addition: Warning message: In View(w) : unable to open display

The solution problem was
