library(texPreview) 

texPreview comes with LaTeX packages built in for each render, but the user can add any TeX library that they have installed on the machine using build_usepackage. This object can then be used in the usrPackages parameter in tex_preview.

build_usepackage(pkg = 'xcolor') 

## [1] "\\usepackage{xcolor}"

build_usepackage(pkg = 'xcolor',options = 'usenames') 

## [1] "\\usepackage[usenames]{xcolor}"

geom.opts=c('paperwidth=35cm','paperheight=35cm','left=2.5cm','top=2.5cm')
use.opts="\\usetikzlibrary{mindmap,backgrounds}"

m <-mapply(
 FUN = build_usepackage,
 pkg = list('times','geometry','tikz'),
 options = list(NULL ,geom.opts ,NULL),
 uselibrary = list(NULL ,NULL ,use.opts)
)

unlist(m) 

## [1] "\\usepackage{times}" 
## [2] "\\usepackage[paperwidth=35cm,paperheight=35cm,left=2.5cm,top=2.5cm]{geometry}"
## [3] "\\usepackage{tikz}" 
## [4] "\\usetikzlibrary{mindmap,backgrounds}"
