No shiny examples will run!

Problems can't get more basic than this. I have updated RStudio, R and all the packages have been updated with the new R version. Here is my problem:

Error: package or namespace load failed for ‘shiny’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
there is no package called ‘later’
Error in runExample("01_hello") : could not find function "runExample"

Seems crazy to me. Any suggestions or help will be very gratefully received.

Do you have the dev version of Shiny installed? The later package is here:

Install with


Thanks, Cole. You prompted me to try installing Shiny from github, which solved the problem anyway.
Thanks for taking the time to offer a suggestion.
