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
