+#' All DEGs Venn Diagram Data
+#'
+#' A dataset containing the differentially expressed genes (DEGs) from four different statistical analysis methods: DESeq2, edgeR, limma, and Wilcoxon test.
+#' This dataset is used for generating Venn diagrams to compare the overlap of DEGs identified by different methods.
+#'
+#' @format A list with the following components:
+#' \describe{
+#'   \item{DESeq2}{A vector of gene IDs or gene symbols identified as DEGs by the DESeq2 method.}
+#'   \item{edgeR}{A vector of gene IDs or gene symbols identified as DEGs by the edgeR method.}
+#'   \item{limma}{A vector of gene IDs or gene symbols identified as DEGs by the limma method. }
+#'   \item{Wilcoxon_test}{A vector of gene IDs or gene symbols identified as DEGs by the Wilcoxon test method. }
+#' }
+#'
+#' @source The data was derived from differential expression analyses performed on a gene expression dataset using four commonly used statistical methods (DESeq2, edgeR, limma, and Wilcoxon test).
