Compare the average power distribution of two SplicedViews using sampling on each segment

Description

Compare the average power distribution of two SplicedViews using sampling on each segment

Usage

compare_avg_power2(
  sv1,
  sv2,
  name1,
  name2,
  num_samples,
  column,
  show_plot = TRUE
)

Arguments

sv1	SplicedView object.
sv2	SplicedView object.
name1	name for first object.
name2	name for second object.
num_samples	number of samples to draw from segments.
column	column name in the data e.g. 'Nose_x_Central_Sitar'.
show_plot	show the plot?

Value

list of two data.frames containing the sampled data.
