Server function to create a count plot for a given gene

Description

countPlotServer() creates a count plot for a given gene from the counts and sample information supplied. The plot is a ggplot2 plot object made using biovisr::scatterplot_with_fill_and_shape(). The plot is rendered to the count_plot plotOutput from the countPlotOutput() function.

Usage

countPlotServer(
  id,
  counts = NULL,
  sample_info = NULL,
  gene_metadata = NULL,
  debug = NULL
)

Arguments

id	namespace id for the UI components. Must match the id provided to the countPlotInput() function.
counts	a reactive counts object. Should contain only numeric columns
sample_info	a reactive object. Represents the samples and associated metadata
gene_metadata	a reactive object. Contains the metadata for the genes present in the counts object.
debug	Turn on debugging message statements

Value

a shiny::reactive() object which is the count plot

Examples

countPlotServer("rnaseq", counts = reactive(rnaseqVis::counts[1:10, 1:20]),
sample_info = reactive(rnaseqVis::sampleInfo[1:20,]),
gene_metadata = reactive(rnaseqVis::gene_metadata[1:10,]))
