DataFusionGDM
Machine Learning for Integrating Partially Overlapped Genetic Datasets
Tools to simulate genetic distance matrices, align and compare them via
multidimensional scaling (MDS) and Procrustes, and evaluate imputation with
the Bootstrapping Evaluation for Structural Missingness Imputation (BESMI)
framework. Methods align with Zhu et al. (2025)

Install
In R:
if (!requireNamespace("remotes", quietly = TRUE)) install.packages("remotes")
remotes::install_github("jiashuaiz/DataFusion-GDM")
Usage
library(DataFusionGDM)
# Simulate a GDM in memory and visualize
res <- run_genetic_scenario("island", n_pops = 40)
res$plots$heatmap()
res$plots$mds()
# Optionally export to CSV if needed (defaults to tempdir)
tmp <- export_simulated_gdm(scenario = "default", n_pops = 40, verbose = FALSE)
# unlink(tmp) # clean up when finished
# Simulate and visualize
source(system.file("examples/simulate_gdm_quick.R", package = "DataFusionGDM"), echo = TRUE)
# MDS + Procrustes
source(system.file("examples/mds_procrustes_demo.R", package = "DataFusionGDM"), echo = TRUE)
# BESMI batch (small demo)
source(system.file("examples/besmi_batch_quick.R", package = "DataFusionGDM"), echo = TRUE)
