ggplot2latex is an R package designed to efficiently save ggplot2 plots in LaTeX TikZ format. The package provides functions to optimize the resulting .tex files by rounding coordinates, removing duplicated elements, and reducing the file size. This ensures that the LaTeX documents are both lightweight and maintain high-quality visualizations.

• Save ggplot2 plots as LaTeX (TikZ) files.
• Optimize .tex files by rounding coordinates.
• Remove duplicated elements to reduce file size.
• Utilities to handle special characters in LaTeX.

To install the package, use the following command in R:

# Install from CRAN (if available)
install.packages("ggplot2latex")

# Or install from GitHub
devtools::install_github("RomanKyrychenko/ggplot2latex")

Here is an example of how to use the save_tex function to save a ggplot2 plot as a LaTeX (TikZ) file:

library(ggplot2)
library(ggplot2latex)

# Create a ggplot2 plot
ggplot_object <- ggplot(mtcars, aes(x = wt, y = mpg)) + geom_point()

# Save the plot as a LaTeX (TikZ) file
save_tex(ggplot_object, "path/to/file.tex")
