Error on version 3.6 on mac

Hi all,

I just updated R to version 3.6 and I have the latest version of RStudio 1.2.1335. I'm running on a Mac OS Sierra 10.12.6 and I never had any major issues with it - until this R update.

Essentially, running the default rmarkdown document with the following chunk:

knitr::opts_chunk$set(echo = TRUE)

will lead RStudio to crash, printing repeatedly on the console the error message:

Error: option error has NULL value
Error: option error has NULL value
Error: option error has NULL value
Error: option error has NULL value

(repeat ad nauseam)

So, my google fu returned the following issue on GitHub:

which basically points out that there might be an issue with .Rprofile. Apparently there is some bug with error handling, in that a line options(error = ) is causing trouble, and deleting that line fixes the problem.

The thing is, my .Rprofile is empty, I don't have one in my project, nor in my home directory, nor in R HOME. So I can't delete what doesn't exist.

If I add a line with some error handling option sure thing, I get the same error as referenced in the GitHub issue. Not very helpful.

The solution suggested,

A temporary workaround is to set rstudio.errors.suppressed to FALSE in your .Rprofile as well.

doesn't work for me either, unless this involves something different than a line like

options(rstudio.errors.suppressed = FALSE)

on .Rprofile.

So I am at a loss on what to do, other than revert back to R 3.5.3 and wait for patch 3.6.1.

Same here, even for Rstudio 1.2.1511.


I just updated to the newest preview version of RStudio (1.2.1522-1) - and it now works for me (it hadn't last week on 1.2.1511 or 1.2.1335) - so try it from here:

Hi all, thanks, I'll try the preview version as well.
