EBSEA {EBSEA}R Documentation

Exon Based Startegy for Expression Analysis of genes

Description

EBSEA takes as input unnormalized counts of exons, normalizes them and then performs a two group comparison of the samples to detect differentially expressed between the groups. Both paired or unpaired comparison are supported. It calculates fold changes, p-values and false discovery rate of the genes between the groups.

Usage

EBSEA(data, group, paired = FALSE, plot = FALSE)

Arguments

data

A dataframe of exon count data

group

A vector indicating the sample groups in the experiment

paired

A logical indicating whether the samples are paired or unpaired. Default: FALSE

plot

A logical indicating whether a volcano plot is visualized. Default: FALSE

Value

EBSEA returns a list of two dataframes. ExonTable is a dataframe that contains exon statistics including log fold change, p-values, adjusted p-values, average expression and fold change. GeneTable is a dataframe that contains the corresponding fold change, log fold change, p-values and false discovery rate.
