WebBioconductor version: Release (3.16) The 'enrichplot' package implements several visualization methods for interpreting functional enrichment results obtained from ORA or GSEA analysis. It is mainly designed to work with the 'clusterProfiler' package suite. All the visualization methods are developed based on 'ggplot2' graphics. WebThe q -value can be interpreted as the false discovery rate (FDR): the proportion of false positives among all positive results. Given a set of test statistics and their associated q -values, rejecting the null hypothesis for all tests whose q -value is less than or equal to some threshold ensures that the expected value of the false discovery ...
