# RMarkdown can't keep authors in separate lines

I have mutiple authors with different affiliations. I am not able to keep them in separate lines. Also see warning message shown at end of this posting.
I actually had it workign file before I upgraded to R3.6.2 with tinytex_0.20 rmarkdown_2.1 .

Any help is appreciated.

the code in Rmd file:

## ################

title: Summary Report
author:

• "John Doe, Mike Mistery, Nance Mistery, Sam Excellent"
• "North America Explorer Team"
• "Christie Outstanding, Jon Goodfellow"
• "North America New Development"
date: "r format(Sys.time(), '%B %d, %Y')"
• \usepackage{titling}
• \pretitle{\begin{center}\LARGE\includegraphics[width=8cm]{blue_sky.png}\[\bigskipamount]}
• \posttitle{\end{center}}
• \usepackage{fancyhdr}
• \usepackage{xcolor}
• \pagestyle{fancy}
• \fancyfoot[CO,CE]{X Company Confidential}
• \fancyfoot[LE,RO]{\thepage}
• \fancypagestyle{plain}{\pagestyle{fancy}}
output:
pdf_document:
toc: true

################

the output in PDF:

################
test1.pdf (311.1 KB)
################

I also see
Warning message:
Package Fancyhdr Warning: \fancyfoot's E' option without twoside option is use less on input line 109. Package Fancyhdr Warning: \fancyfoot's E' option without twoside option is use
less on input line 110.
Package Fancyhdr Warning: \headheight is too small (12.0pt):
Make it at least 23.6612pt.
We now make it that large for the rest of the document.
This may cause the page layout to be inconsistent, however.

This discussion here:

The default latex template is now the one from Pandoc directly and it does put the authors with an \and. See the template.

If you want multiple author differently organized, I think you need to provide your own template. There is also a trick to change the meaning of the \and latex command in the discussion on GH.

If you downgrade, you may encounter other issue. You can try the trick I posted on the GH issue

Hello world.


Could work for you if you don't use the \and command elsewhere than in author.

Excellent, That solved my problem!
Glad I have not downgraded RMarkdown as I am concerned it may cause other issues.

Thanks so much!
