Plot Volcano Plot of Differential Expression Results — plot_exp

Generates a volcano plot based on the results of differential expression analysis, highlighting upregulated and downregulated genes, with labels for top significant genes.

Usage

plot_exp_volcano(
  diffexp,
  nb = 10,
  title = "Volcano Plot of Differential Expression",
  color_up = "#0072B2",
  color_down = "#D55E00",
  color_ns = "gray80",
  fname = NULL
)

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
color_up: Color used for upregulated genes (default is "#0072B2").
color_down: Color used for downregulated genes (default is "#D55E00").
color_ns: Color used for non-significant genes (default is "gray80").

Value

A `ggplot` object representing the volcano plot.
