Get a scatter plot showing correlation between replicates.
Arguments
- x
an abject of class "parcutils". This is an output of the function
run_deseq_analysis()
.- samples
a character vector denoting samples to plot in scatter plot, default
NULL
. If set to NULL all samples are accounted.- genes
a character vector denoting genes to consider in scatter plot, default
NULL
. If set to NULL all genes are accounted.#'
Examples

count_data <- readr::read_delim(count_file, delim = "\t")
