VolcanoDEGRE {DEGRE} R Documentation

## Create a volcano plot to visualize the proportion of downregulated and upregulated genes by applying a log2FC cutoff.

### Description

Create a volcano plot to visualize the proportion of downregulated and upregulated genes by applying a log2FC cutoff.

### Usage

VolcanoDEGRE(
results,
log2FC_cutoff = 1,
font.x = 10,
font.y = 10,
font.tickslab = 10,
downregulated_color = "coral2",
upregulated_color = "cornflowerblue",
xlab = "log2Foldchange",
ylab = "-log10(P-value)",
legend_position = "right",
legend.title = "Regulation"
)


### Arguments

 results a data.frame object. It receives the output of the DEGRE function, filtered or not, as input. log2FC_cutoff it stores the cutoff of the log2FoldChange. The default is 1. padj it stores the cutoff of the P-adjusted value (Q-value). The default is 0.05. font.x the font size of the x axis. The default is 10. font.y the font size of the y axis. The default is 10. font.tickslab the font size of the ticks lab. The default is 10. downregulated_color the colors of the downregulated genes. The default is "coral2". upregulated_color the colors of the upregulated genes. The default is "cornflowerblue". xlab the x lab text. The default is "log2Foldchange". ylab the y lab text. The default is "-log10(P-value)". legend_position you need to specify here the position of the legend. The default is "right". legend.title the title of the legend. The default is "Regulation".

### Value

No return value, called for side effects

### Examples

dir <- system.file("extdata", package = "DEGRE")
# Running the VolcanoDEGRE function
VolcanoDEGRE(results = results_DEGRE_example,
log2FC_cutoff = 1,
