8 years ago Confirmed fixed in commit e4127e60947678a9ced3b762d3cad59f0352876e by manually editing all lines to be < 80 chars.
I made use of this little bash trick to identify lines > 80 chars: grep '.{80}' filename but I still had to manually edit the offenders to wrap to the next line.
Then I again set warnings_are_errors: true and confirmed the travis build worked. (I did not find a way to reproduce the warning locally.)
If you set this to true AND check in code that causes documentation to be rebuilt, you will see a bunch of warnings that now break the build. These warnings should be fixed so we can set warnings_are_errors: true, which is required for CRAN.
Here is an example of build output when warnings_are_errors: true. The gist is we have too many lines in our documentation that are too wide for the pdf. I just don't have time to fix them while I'm in the middle of other work now.
