-## Resubmission
-
-This is a resubmission. Following Martina Schmirl's email of 2019-07-07:
-
-* I have amended the title to remove the redundant R.
-
-* I have noted for each of the two remaining instances of `\dontrun{}` that
-  these examples make calls to Python (missing additional software). 
-
-* I have amended an example-set to use `donttest{}` as these examples, as run, 
-  do not call Python.
-
-This is a resubmission. Following Uwe Ligge's email of 2019-06-28:
-
-* I have added Python and Altair as `SystemRequirements` - my apologies for 
-  missing this.
-
-* The functions from the other package, 'vegawidget', are exported. 
-
-  The 'vegawidget' package offers functions to render 'Vega' and 'Vega-Lite'
-  specifications in the browser. The 'altair' package lets you  
-  build Vega-Lite specifications by exposing the Python Altair library. 
-
-  As such, 'altair' exports the 'vegawidget' rendering-functions.
-  There may be developed other packages that build Vega and Vega-Lite 
-  specifications, for which 'vegawidget' offers a common set of 
-  rendering functions.
-
-  I have reassessed the functions that are re-exported. I have deprecated three
-  of these functions, in favor of using 'vegawidget' directly.
