genes_to_label

Character: a vector of selected genes. Default: "NULL".

label_size

Numeric: gene label size. Default: 5, min: 0.

base_size

Numeric: base font size. Default: 12, min: 0.

title

Character: main plot title. Default: "Gene ranking dotplot".

xlab

Character: title of the xlab. Default: "Ranking of differentially expressed genes".

ylab
