savetexvalue

savetexvalue helps saving and managing values calculated in R for integration in projects written in LaTeX in an automatic and reproducible way. savetexvalue uses special formatted .tex files containing pairs of values and command names to be used in LaTeX.

Installation

You can install savetexvalue from GitHub with:

# install.packages("devtools")
devtools::install_github("Ori-Shoham/savetexvalue")

Example

Suppose you work on a project analyzing the sepal length of irises.

library(savetexvalue)
library(dplyr)
data(iris)

# These are the computations
avg_sep_length <- iris %>% 
  group_by(Species) %>% 
  summarise(sep_length_avg = mean(Sepal.Length))

prop_greater_6 <- iris %>% 
  group_by(Species) %>% 
  summarise(prop_greater = mean(Sepal.Length > 6))

# Save the values:
path <- tempdir()
save_tex_value(values = avg_sep_length$sep_length_avg,
               names = paste0(avg_sep_length$Species,"Avg"),
               file_name = "iris_calc",
               path = path)
save_tex_value(values = prop_greater_6$prop_greater,
               names = paste0(prop_greater_6$Species,"PerGreaterSix"),
               file_name = "iris_calc",
               path = path,
               percent = T,
               accuracy = 0.1)

The contents of iris_calc.tex should now be:

\newcommand\setosaAvg {5.01}
\newcommand\setosaPerGreaterSix {0.0\%}
\newcommand\versicolorAvg {5.94}
\newcommand\versicolorPerGreaterSix {40.0\%}
\newcommand\virginicaAvg {6.59}
\newcommand\virginicaPerGreaterSix {82.0\%}

The values are ready to be used in your paper! The .tex file for your paper could look like this:

\documentclass{article}
\begin{document}

\input{iris_calc}
We find that the Virginica species tends to have longer sepals than the Versicolor species.
Virginicas' sepals are \virginicaAvg{} inches long on average and \virginicaPerGreaterSix{}
of them are longer than 6 inches while Versicolors' sepals are only \versicolorAvg{}
inches long on average and only \versicolorPerGreaterSix{} of them are longer than 6 inches.
