Two authors in Rmarkdown's isoslide

How can I show two authors side by side in my isoslide.
Here, I want to show author1 on left and author2 at right.

---
title: This is my title
author: 
- "Author1"
- "Author2"
date: "`r format(Sys.time(), '%d %B %Y')`"
output: 
  ioslides_presentation:
    css: slide.css

Hi @meitei,

A lame workaround would be to just list both authors in the first author slot, like:

---
title: "Untitled"
author: 
  - "First Author - Second Author"
output: ioslides_presentation
---

Or, modify the default HTML template, in particular this section:

// Author information
      presenters: [
      $for(author)$
      {
        name: $if(author.name)$ '$author.name$' $else$ '$author$' $endif$,
        company: '$author.company$',
        gplus: '$author.gplus$',
        twitter: '$author.twitter$',
        www: '$author.www$',
        github: '$author.github$'
      },
      $endfor$
      ]

and then include it in your Rmd file:

---
title: "Untitled"
author: 
  - "First Author"
  - "Second Author"
output: 
  ioslides_presentation:
    template: my-custom-template.html
