Plot distribution of a metric values as boxplots depending of bins. If the bin is absent from gr, a single boxplot is drawn.

Usage

plotBoxMetric(
  gr,
  metric = "expr",
  title = "Metric",
  trans_func = function(x) x,
  ylim = NULL,
  ylab = "metric",
  palette = colorRampPalette(c("magenta", "black", "green"))
)

Arguments

gr	a GRanges input
metric	name of the column in gr metadata containing scores.
title	title of the plot.
trans_func	A function to transform value of x before ploting. Useful to apply log10 transformation (i.e. with trans_func = function(x) log10(x+1)).
ylim	limit of the y axis; format: ylim = c(min, max)
ylab	y-axis title
palette	a function that returns a palette of n colors.

Value

Display a plot.

Examples

data("stackepi")
plotBoxMetric(
       stackepi,
       trans_func = function(x) x,
       metric = "exp",
       title = "Metric"
