)

Arguments

x

SummarizedExperiment, Data object for which differentially enriched proteins are annotated (output from test_diff() and test_diff_deg()).

contrast

Character. Only plot on certain contrasts.

point_alpha

Numeric(1), between 0 to 1, transparency value for the points (0 = transparent, 1 = opaque)

sig_color

Charecter(1), Color to use to mark differentially expressed genes. Defaults to red

hlines

Numeric(1), The y coordinate (in absolute value) where to draw horizontal lines, optional

title

A title for the plot, optional

xlab

X axis label, defaults to "mean of normalized counts - log10 scale"

ylim

Vector of two numeric values, Y axis limits to restrict the view.

add_rug

Logical, whether to add rug plots in the margins

intgenes

Vector of name, highlighted on plot by intgenes_color column is provided in x, or else the identifiers specified in the row names

intgenes_color

Character(1), The color to use to mark the genes on the main plot.

intgenes_size

The point size of intgenes.

label_fontsize

Numeric(1), The fontsize of labels_intgenes

labels_repel

Logical, whether to use geom_text_repel for placing the labels on the features to mark

Value

A ggplot object
