JSCS Brownian excursion/meander figures

R code for producing the figures used in the JSCS submission. All scripts run from this directory and read helpers in my_functions_r1.R.

Requirements

• R (>= 4.0 recommended)
• Packages: ggplot2, latex2exp, MASS, reshape2, gridExtra

How to run

• Excursion plots (uses cached draws if present, writes output to Figures/Figure_excursion.png):

  Rscript Figure_0004_r1.R

• Other figures follow the same pattern; each script sources my_functions_r1.R and writes plots to the working directory (or Figures/ for updated scripts).

Repository layout

• Figure_0001_r1.R .. Figure_0006.R: scripts that create individual figures.
• my_functions_r1.R: core math helpers and samplers.
• Figures/: output folder for generated images (created automatically).
