3.4 RMarkdown

To ensure you are up to date, run the following script to install the packages.

install.packages("rmarkdown")
install.packages("knitr")
install.packages("tinytex")
install.packages("here")
install.packages("tidyverse")
install.packages("broom")
install.packages("fs")
install.packages("usethis")

3.5 A note on PDF

rmarkdown documents can be compiled to PDF, which is a great feature. In order to convert the documents to PDF, they use a software called LaTeX () (pronounced la-tek or lay-tek).

Installing LaTeX can be a pain, but thankfully there is an easier way to install it - tinytex. tinytex is an R package that installs a sane, lightweight (<200Mb) version of LaTeX.

tinytex::install_tinytex()

If you get the following error, this is good! As it means that TeX has already been installed:

Error: Detected an existing tlmgr at /usr/local/bin/tlmgr. It seems TeX Live has been installed (check tinytex::tinytex_root()). You have to uninstall it, or use install_tinytex(force = TRUE) if you are sure TinyTeX can override it (e.g., you are a PATH expert or installed TinyTeX previously).

3.5.1 Problem solving with LaTeX

If you have any problems with installing tinytex, I recommend you check out the tinytex FAQ page.

3.6 Test Script

library(rmarkdown)
library(knitr)
library(tinytex)
library(here)
