a) Duncan, he provided sessionInfo below his reprex.
b) Patrick: you appear to be trying to use a common file to generate multiple
output formats. I will caution you that I have found considerable
disappointment in trying that, and suggest that you focus your efforts on one
output format for each Rmd file.
c) You can add out.width="100%" and out.height="100%" to your chunk to fix the
scaling problem. This method is HTML-specific... you would need different
strings for LaTeX output.
d) Note that the help files for the rmarkdown output functions are often very
interesting. e.g.
?rmarkdown::ioslides_presentation
