I'm following the Shiny tutorial on building widgets (http://shiny.rstudio.com/articles/js-build-widget.html)
Everything up to the line
works well; the app displays "hello world" perfectly fine. However, despite best efforts following the subsequent instructions, the gauge doesn't display when I continue with the tutorial. Even though R doesn't display any errors, the "Viewer" tab of RStudio is completely blank.
Do others have similar problems? Or does the tutorial work? I'm using Windows 7 with Version 1.1.442 of RStudio and R version 3.4.4.
