In luciorq/txomics: Functional Analysis and Visualization of Transcriptomic Data

Description

Plot a heatmap from expression data

Usage

plot_heatmap(tx, sample_table, color_by = NULL, num = NULL,
  scale = "row", show_rownames = FALSE, ...)

Arguments

tx	txi object, matrix or data frame with trancript abundance
sample_table	metadata data frame, containing description of each sample and experimental design
color_by	variable from sample table to group samples in the plot
num	number of genes to plot, filtering by variance between samples, if num is negative, it is used the absolute num of genes with smaller, if num is NULL all genes are used. default = NULL.
scale	logical, default = "row", normalize data by row, column or none
