+\title{Differential Gene Expression Analysis using 'edgeR'}
+\usage{
+edgeR_analyze(
+  tumor_file,
+  normal_file,
+  output_file,
+  logFC_threshold = 2.5,
+  p_value_threshold = 0.01
+)
+}
+\arguments{
+\item{tumor_file}{Path to the tumor data file (RDS format).}
+
+\item{normal_file}{Path to the normal data file (RDS format).}
+
+\item{output_file}{Path to save the output DEG data (RDS format).}
+
+\item{logFC_threshold}{Threshold for log fold change for marking up/down-regulated genes.}
+
+\item{p_value_threshold}{Threshold for p-value for filtering significant genes.}
+}
+\value{
+A data frame of differential expression results.
+}
+\description{
+This function performs differential gene expression analysis using the 'edgeR' package.
+It reads tumor and normal expression data, merges them, filters low-expressed genes,
+normalizes the data, performs edgeR analysis, and outputs the results along with information
+on gene expression changes.
