tidyheatmaps

The goal of tidyheatmaps is to simplify the generation of publication-ready heatmaps from tidy data. By offering an interface to the powerful pheatmap package, it allows for the effortless creation of intricate heatmaps with minimal code.

Installation

You can install the released version of tidyheatmaps from CRAN with:

install.packages("tidyheatmaps")

And the development version from GitHub with:

# install.packages("devtools")
devtools::install_github("jbengler/tidyheatmaps")

Usage

Given a tidy data frame of gene expression data like data_exprs, you can easily generate a customized heatmap. The full documentation can be found here.

library(tidyheatmaps)

tidyheatmap(data_exprs,
            rows = external_gene_name,
            columns = sample,
            values = expression,
            scale = "row",
            annotation_col = c(sample_type, condition, group),
            annotation_row = c(is_immune_gene, direction),
            gaps_row = direction,
            gaps_col = group
)
