Examples

ngene <- 10
condition1_pvals <- stats::runif(ngene)
condition2_pvals <- stats::runif(ngene)
condition3_pvals <- stats::runif(ngene)
gene_names <- paste("Gene", 1:ngene, sep="")
gene_dat <- data.frame(Gene=gene_names,
                       condition1_pvals=condition1_pvals,
                       condition2_pvals=condition2_pvals,
                       condition3_pvals=condition3_pvals)
ggdat <- gather(data=gene_dat, key="comparison",
                       value="pvalue",
                       condition1_pvals, condition2_pvals,
                       condition3_pvals, -Gene)
violinp <- ggplot(ggdat, aes(x=comparison, y=pvalue)) +
geom_violin() + labs(x="Comparison", y="p-value",
title="Violin plots of p-values across comparison types")
