Usage

sideViolin(y, cond, MAP = NULL, logT = TRUE, title.gene = "",
  conditionLabels = unique(cond), axes.titles = TRUE)

Arguments

y

Numeric vector of data to plot.

cond

Vector of condition labels corresponding to elements of x.

MAP

List of MAP partition estimates with conditions as list items and samples as elements (integer indicating which cluster each observation belongs to; zeroes belong to cluster 1)

logT

Logical that indicates whether to take the log(x+1) transformation.

title.gene

Character vector that contains the gene name that you are plotting.

conditionLabels

Character vector containing the names of the two conditions.

axes.titles

Logical indicating whether or not to include axes labels on plots.

Value

ggplot object
