gWidgetsRGtk2 warning

[briancohn]

After running

install.packages('retistruct')

In R 3.3.1 (2016-06-21)

When I run
retistruct::retistruct()
I get a message about gWidgets not being available on CRAN:

Loading required package: gWidgetsRGtk2

1. What's the right way to move forward from here?
2. Does this affect current/future operation of retistruct?

Thanks so much David!

Hmm... This is a bit tricky to diagnose, as I don't have a Mac. There are problems getting GTK binaries for Mac; see #4 for a summary of how to deal with this. I'd suggest as a first course of action, closing R, then opening it again and trying retistruct::retistruct() again. Then look at the ways forward in #4.

gWidgets is still on CRAN, so there shouldn't be a problem there: https://cran.r-project.org/web/packages/gWidgets/index.html

The github version of Retistruct (which will be the next release) uses the gWidgets2 package, which is a rewrite of gWidgets.

Sounds good! Thanks
