Arguments

data	differential expression results
fold_change	column containing fold change data (x-axis)
p_value	column containing p-value data (y-axis is -log10(p_value))
color	column for color
label	column for text annotation
annotations	features to be annotated
annotations_if_threshold	features to be annotated iff they meet the thresholds
n_annotate_top	number of top DE genes to annotate
p_value_threshold	maximum p-value
fold_change_threshold	minimum absolute fold change threshold
p_value_rank_threshold	maximum p-value rank threshold
alpha	alpha of points
facet_rows	columns for faceting by row
facet_columns	columns for faceting by column
facet_type	either "wrap" or "grid", corresponding to facet_wrap and facet_grid respectively
...	other params passed into either facet_wrap or facet_grid, depending on facet_type parameter

Value
