penguins DF shows a blank Viewer Pane in latest Rstudio

[sfd99]

Datacomb is a super-nice pkg!.
Thanks, Chris!
Works 100% with iris, diamonds, mtcars...

But no chart at all
is shown for:
library(palmerpenguins)
Datacomb(penguins)

The penguins DF
shows a totally blank Viewer Pane
in the latest Rstudio.
No datacomb chart...

What am I missing?.

• USEFUL SUGGESTION for datacomb:
  In addition to using the mouse,
  it would be really nice and easy,
  to be able to pan up/down the chart rows
  with the Keyboard's UP/DOWN arrows! .
