highlighting upregulated and downregulated genes, with labels for top significant genes.
Usage
plot_exp_volcano(
diffexp,
nb = 10,
title = "Volcano Plot of Differential Expression"
)
Arguments
- diffexp
A data frame containing differential expression results. Must include:
- `log2FoldChange`: The log2 fold change values for each gene.
- `padj`: The adjusted p-value for each gene.
- nb
The number of genes that have an annotation
Value
A `ggplot` object representing the volcano plot.
