Description
When trying to run the attached code, I see an error from invoking rmarkdown:render(), unfortunately Package Manager does not list pdflatex as a dependency which must be installed it only mentions

yum install -y libicu-devel
yum install -y epel-release
yum install -y pandoc

Package Manager version 1.2.4.1-5

R version 4.0.2 (2020-06-22) -- "Taking Off Again"
