In bulkAnalyseR: Interactive Shiny App for Bulk Sequencing Data

Create a scatter plot of expression between two samples of an experiment

Description

This function creates a scatter plot between two samples.

Usage

scatter_plot(
  sub.expression.matrix,
  anno,
  genes.to.highlight = c(),
  log.transformation = TRUE
)

Arguments

sub.expression.matrix	subset of the expression matrix containing only the two selected samples
anno	annotation data frame containing a match between the row names of the expression.matrix (usually ENSEMBL IDs) and the gene names that should be rendered within the app and in output files; this object is created by generateShinyApp using the org.db specified
genes.to.highlight	vector of gene names to highlight. These should match entries in the anno NAME column.
log.transformation	whether expression should be shown on log (default) or linear scale

Value

The scatter plot as a ggplot object.

Examples

expression.matrix.preproc <- as.matrix(read.csv(
  system.file("extdata", "expression_matrix_preprocessed.csv", package = "bulkAnalyseR"), 
  row.names = 1
))[,1:2]

print(scatter_plot(expression.matrix.preproc, c()))
