transTarget

transTarget is an R package for visualizing genome-wide trans-acting genomic interactions using arc plots.

It is designed to map interactions from a single point (e.g. eRNA, enhancer, locus, mutation, gene) to multiple distal genomic targets across chromosomes using a concatenated genome representation.

📦 Installation

• devtools::install_github("nataliabenova/transTarget")

---

🚀 Quick Start

1. Load library

library(transTarget)

2. Load example dataset

data(eRNA_interactions)

3. Generate plot

arc_plot( eRNA_interactions, s = "support", l = "ID.y", n_bins = 2 )

Input Data Format

The input data frame must contain:

• ID.x — anchor ID (must be a single unique value)
• ID.y — target ID
• chr.x, start.x, end.x — anchor coordinates
• chr.y, start.y, end.y — target coordinates

Optional:

• support — numeric evidence score (otherwise computed automatically)
