ggplotCounts {ideal}R Documentation

Plot normalized counts for a gene

Description

Plot for normalized counts of a single gene, with jittered points superimposed on the boxplot

Usage

ggplotCounts(dds, gene, intgroup = "condition", annotation_obj = NULL,
  transform = TRUE)

Arguments

dds

A DESeqDataSet object.

gene

A character, specifying the name of the gene to plot

intgroup

Interesting groups: a character vector of names in colData(dds) to use for grouping

annotation_obj

A data.frame object, with row.names as gene identifiers (e.g. ENSEMBL ids) and a column, gene_name, containing e.g. HGNC-based gene symbols. Optional.

transform

Logical value, corresponding whether to have log scale y-axis or not. Defaults to TRUE.

Details

Note: this function relies on the plotCounts function of DESeq2, therefore pseudocounts of 0.5 are added to each point

Value

An object created by ggplot

Examples

library(airway)
data(airway)
airway
dds_airway <- DESeq2::DESeqDataSetFromMatrix(assay(airway),
                                             colData = colData(airway),
                                             design=~cell+dex)
ggplotCounts(dds_airway,
             gene = "ENSG00000103196", # CRISPLD2 in the original publication
             intgroup = "dex")
