draw_genes_barplot: Stacked Barplot of Low Expression Genes by Chromosome

In insightsengineering/hermes: Preprocessing, analyzing, and reporting of RNA-seq data

Stacked Barplot of Low Expression Genes by Chromosome

Description

This creates a barplot of chromosomes for the AnyHermesData object with the proportions of low expression genes.

Usage

draw_genes_barplot(
  object,
  chromosomes = c(seq_len(22), "X", "Y", "MT"),
  include_others = TRUE
)

Arguments

object	(AnyHermesData) input.
chromosomes	(character) names of the chromosomes which should be displayed.
include_others	(flag) option to show the chromosomes not in chromosomes as "Others".

Value

The ggplot object with the histogram.

Examples

object <- hermes_data

# Display chromosomes 1-22, X, Y, and MT. Other chromosomes are displayed in "Others".
# To increase readability, we can have flip the coordinate axes.
draw_genes_barplot(object) + coord_flip()

# Alternatively we can also rotate the x-axis tick labels.
draw_genes_barplot(object) + theme(axis.text.x = element_text(angle = 90, vjust = 0.5, hjust = 1))

# Display chromosomes 1 and 2. Other chromosomes are displayed in "Others".
draw_genes_barplot(object, chromosomes = c("1", "2"))

# Display chromosomes 1 and 2 only.
draw_genes_barplot(object, chromosomes = c("1", "2"), include_others = FALSE)
