Two are the steps needed to create a R/tex report, a starter R script to create the final pdf, and a .Rnw file where all our code will be stored.
The starter script
The starter script has to do two basic functions:
- Load and pass the Rnw file to the knit command of the
knitrpackage. This process is called weaving. This will execute the R code and produce a series of files among which there’s a .tex file that we would normally use intexstudio. - Execute twice the .tex file in order to create the final PDF report
my.knit = knitr::knit("document.Rnw")
## document.tex is the latex file that will be compiled by the two following command:
system(paste0("pdflatex ", "document.tex"))
system(paste0("pdflatex ", "document.tex")) By executing the file starter.R you will create the latex document.
I recommend to use the command:
R CMD BATCH starter.RAlternatively you can copy/paste the three lines of code on the command line.
The command knit will create the file document.tex.
The Rnw file
The .Rnw (or Sweave) file is in essence a .tex file in which it is possible to insert blocks of R code.
The structure of the file follows the normal structure of a LaTeX work starting with the declaration of the document class but at any point in the code you can add R blocks of code.
Those are defined between two elements: a <<…>> in which the setting of the R code blocks are passed and a @, that defines its end.
