I am trying to build a beamer presentation using rmarkdown. In my presentation I want to include tables using the kable, and kableExtra packages. I am having issues with this because one of the LaTex packages that kableExtra requires is already loaded by the beamer presentation with different options. This is the error message that I receive.
! LaTeX Error: Option clash for package xcolor.
I have been searching for a fix for this but have not had any luck. I have found solutions on the LaTex pages, here and here, but I do not know LaTex and I have not figured out how to apply these solutions in the rmarkdown arena. I have tried looking at the Latex templates in rmarkdown, but I do not understand it well enough to try and implement these solutions.
Any thoughts or solutions would be much appreciated. Here is just a quick sample of the .Rmd that gives the error.
---
title: "Untitled"
author: "Author"
date: "April 28, 2018"
output:
beamer_presentation:
keep_tex: true
header-includes:
- \usepackage[table]{xcolor}
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE)
library(knitr)
library(kableExtra)
dt <- mtcars[1:5, 1:6]
```
## Slide with R Output
```{r cars, echo = TRUE}
kable(dt, format = "latex")
```
## Slide with Plot
```{r pressure}
plot(pressure)
```
The linked answer on the TeX stackexchange suggests adding table to the class options for the document e.g. \documentclass[a4paper,table]{article}. In order to do this in RMarkdown, you can use a classoption: line in your YAML header:
---
title: "Untitled"
author: "Author"
date: "April 28, 2018"
classoption: table
output:
beamer_presentation:
keep_tex: true
