Just a quick preface, I have looked into all the other stackoverflow comments I can find related to this error and cannot still correct or identify my issue based on existing posts.
I am currently having an issue getting past a warning that's occurring on linux based builds for my vignette. The warning is:
LaTeX Error: Option clash for package xcolor.
The check results are here: https://win-builder.r-project.org/incoming_pretest/DEVis_1.0.1_20181220_164555/Debian/00check.log
Windows and OS X builds work fine, but I don't have access to a debian machine that I can reproduce this on. I currently cannot reproduce this issue on my side, and travis-ci checks do not seem to produce this warning for linux on ubuntu. I can only see it currently when submitting an update to my package and failing the cran auto-checks.
I have recently changed from PDF vignette to html-based, and am not sure why latex packages would even be loading in this case. I have attempted to correct for it based on this post, which claims the issue is a conflict between kableExtra and xcolor.
Some relevant sections of code from the vignette might include:
vignette: |
%\VignetteIndexEntry{DEVis}
%\usepackage[utf8]{inputenc}
%\usepackage[table]{xcolor}
%\VignetteEngine{knitr::knitr}
---
```{r loadData, echo = F, eval = TRUE}
#load("../data/exampleData.Rda")
knitr::opts_knit$set(root.dir ='../vignettes/')`
knitr::opts_chunk$set(fig.path='figure/graphics-',
cache.path='cache/graphics-',
fig.align='center',
external=TRUE,
echo=TRUE,
warning=FALSE,
fig.pos='H'
)
a4width<- 8.3
a4height<- 11.7
library(kableExtra)
library(rmarkdown)
library(knitr)
options(knitr.table.format = "html")
options(kableExtra.latex.load_packages = FALSE)

I would appreciate any insight anyone can offer into this issue, as I cannot update my package until I get to the bottom of this! Thanks very much in advance!
As it turns out, the answer is to remove the following lines:
%\usepackage[utf8]{inputenc}
%\usepackage[table]{xcolor}
These are LaTeX lines apparently and on debian cran builds are causing the above problem.
