MiamiPlot

R function to create a ggplot2 based miami plot

Installation

Install directly from github using devtools

library(devtools)
install_github("juliedwhite/miamiplot", build_vignettes = TRUE)

Load the package each time you use it:

library(miamiplot)

Usage

See the vignette for more examples:

vignette("miamiplot")

Take a look at the built-in data:

head(gwas_results)

Basic miami plot using built-in data, with positive beta values in the upper plot and negative beta values in the lower plot.

ggmiami(data = gwas_results[which(gwas_results$study == "A"),], 
        split_by = "beta", split_at = 0, p = "pval", 
        upper_ylab = "Positive beta values",
        lower_ylab = "Negative beta values")

If you'd like to construct your own code "from scratch" (maybe you want to change the appearance and position of the axes or something else), there is a tutorial using the background code from the package in vignette("scratch_miamiplots").
