Unified LocusComparer Plotting Function — locuscomparer • functions

This function serves as a single entry point for creating LocusComparer plots. It can generate individual scatter plots, LocusZoom plots, or combined plots.

Usage

locuscomparer(
  data_coloc_exposure,
  data_coloc_outcome,
  SNP_causal_exposure,
  type = c("combined", "scatter", "locuszoom"),
  trait1_title = "exposure",
  trait2_title = "outcome",
  legend = TRUE,
  legend_position = "bottomright"
)

Arguments

data_coloc_exposure: (data.frame) Data frame for exposure. Must have columns snp, pval, position, LD.
data_coloc_outcome: (data.frame) Data frame for outcome. Must have columns snp, pval.
SNP_causal_exposure: (string) rsID of the causal SNP to highlight.
type: (string) Type of plot to generate: "combined", "scatter", or "locuszoom". Default is "combined".
trait1_title: (string) Title for trait 1. Default "exposure".
trait2_title: (string) Title for trait 2. Default "outcome".
