ave_power_over_splices {movementsync}

Calculate mean average power over splices using a splicing table

Description

Randomly generates splices from a splicing table and calculates average power for each segment and splice. Calculates the mean average power over the random splices for each segment and period. Compares with the average power for the original splice.

Usage

ave_power_over_splices(
  jv,
  splicing_df,
  num_splices,
  column,
  sampling_type = "offset",
  rejection_list = list(),
  include_original = TRUE,
  show_plot = TRUE
)

Arguments

jv

JoinedView object.

splicing_df

Splice object.

num_splices

number of randomly chosen splices.

column

name of data column on which to calculate average power.

sampling_type

either 'offset' or 'gap'.

rejection_list

list of splice objects that random splices must not overlap.

include_original

include the original splice in output? (Default is TRUE).

show_plot

show a plot? (Default is TRUE).

Value

data.frame of splice segments and their average power.
