This reproducible R Markdown analysis was created with workflowr (version 1.7.1). The Checks tab describes the reproducibility checks that were applied when the results were created. The Past versions tab lists the development history.
Great! Since the R Markdown file has been committed to the Git repository, you know the exact version of the code that produced these results.
Great job! The global environment was empty. Objects defined in the global environment can affect the analysis in your R Markdown file in unknown ways. For reproduciblity it’s best to always run the code in an empty environment.
The command set.seed(20240702) was run prior to running
the code in the R Markdown file. Setting a seed ensures that any results
that rely on randomness, e.g. subsampling or permutations, are
reproducible.
Great job! Recording the operating system, R version, and package versions is critical for reproducibility.
Nice! There were no cached chunks for this analysis, so you can be confident that you successfully produced the results during this run.
Great job! Using relative paths to the files within your workflowr project makes it easier to run your code on other machines.
Great! You are using Git for version control. Tracking code development and connecting the code version to the results is critical for reproducibility.
The results in this page were generated with repository version 30a553c. See the Past versions tab to see a history of the changes made to the R Markdown and HTML files.
Note that you need to be careful to ensure that all relevant files for
the analysis have been committed to Git prior to generating the results
(you can use wflow_publish or
wflow_git_commit). workflowr only checks the R Markdown
file, but you know if there are other scripts or data files that it
depends on. Below is the status of the Git repository when the results
were generated:

These are the previous versions of the repository in which changes were

MATHPOP
Welcome to MATHPOP, a R software for inferring globular
cluster (GC) counts in low-surface brightness galaxies (LSBGs) and
ultra-diffuse galaxies (UDGs). The R code in this repo is
written based on the framework of MArk-dependently THinned POint Process
(MATHPOP) proposed by Li et al. (2024), “Discovery of Two
Ultra-Diffuse Galaxies with Unusually Bright Globular Cluster Luminosity
Functions via a Mark-Dependently Thinned Point Process
(MATHPOP)”.
R and RStudio
R is a powerful open source language designed for
statistical computing and data analysis. Download R at The Comprehensive R Archive Network
(CRAN) and RStudio.
R is the base language environment that executes all
programs and code. RStudio is an integrated user interface
wrapper that makes the base R easy to use (similar to
Jupyter Notebook for Python).
How to use R
If you are an absolute beginner of R, there are a LOT of
resources and tutorials teaching how to use R. The best (in
my opinion) resource is the book ‘R for Data Science’ by Hadley
Wickham, and here is a free online
version of the book.
Install the MATHPOP R package
To use MATHPOP for your own data, download and install the MATHPOP
R package by running the following code in R
console.
devtools::install_github('davidolohowski/MATHPOP_R_pkg')Quick Start
For a quick example of how to use MATHPOP, see this vignette.
The MATHPOP framework also proposes to use a probabilistic GC catalog, see this tutorial on how to obtain a probabilistic GC catalog from point sources.
MATHPOP Paper Code
This repo also contains various vignettes for the main analysis done in different sections of the Li et al. (2024) paper, and they are all reproducible and accessible in this repo.
