SecurityError when previewing Notebook after R 3.5.0 upgrade

[mfar]

After updating to R 3.5.0 (Mac OS X 10.12.6) RStudio notebook behaviour has become flaky. Notebooks will sometimes fail to be generated at all, table formatting has been lost and there is frequently the message:

Error creating notebook: Exception caught: (SecurityError) : Blocked a frame with origin "http://127.0.0.1:44273" from accessing a cross origin frame.

This occurs even with a new .Rmd file and persists even with latest daily build (RStudio 1.2.612)

Work is underway on the table formatting...

Issues with R Markdown/Notebook in R 3.5.0 - Not displaying tibble/df nicely inline

Thanks for the bug reports, everyone. It looks like this is an IDE issue (we're running afoul of some changes in S3 dispatch behavior in R 3.5.0). I've filed an issue here: and we'll try to find a fix soon.

I don’t know if the rest is related or not, but posting as many details as you can (and steps to reproduce other flakiness, if possible) can’t hurt!

Thanks @jcblum

I get the 'SecurityError' just by

• restarting RStudio

• New File

• R Notebook

• save

• run chunk

• click 'Preview Notebook'

This is still a problem in RStudio daily build 1.2.650.
Downgrading to R 3.4.4 (completely uninstalling 3.5.0 and re-installing 3.4.4) did not help.
Downgrading to RStudio release version 1.1.453 fixed the problem.
But I don't recall this happening with daily build 1.2.618.
Somehow this has cropped up between RStudio 1.1 and 1.2.

New is not always better

[tgrushka]

Yeah, duh. Well, I had upgraded to the daily build to resolve a different RStudio problem with rmarkdown / knitr. Go figure.

roxygen2 does not work with R 3.5.0. OK with R 3.4.4
