#Tex Breaking Example
This repo demonstrates a real life usage of the qdapTools function loc_split. We create a fake .tex document and then use loc_split to break into sections.
library(qdap); library(qdapTools); library(knitr)headers <- sprintf("\\section{%s}",
unlist(TC(random_sent(3, 5, range=c(0, 1),
endmark.fun = function() ""))))
subheaders <- sprintf("\\subsection{%s}",
unlist(TC(random_sent(6, 5, range=c(0, 1),
endmark.fun = function() ""))))
content <- lapply(replicate(6, unbag(random_sent())), strwrap)
ref_maker <- function(package){
cit <- capture.output(citation(package))[-c(1:3)]
out <- loc_split(cit, which(cit == ""))[[1]]
out[1] <- Trim(out[1])
c("", out)
}
