copy_number_density: Copy number density estimation

In crukci-bioinformatics/rascal: Shiny app and functions for scaling relative copy number data to absolute values

Description

Obtain density estimates for the distribution of the given copy number values.

Usage

copy_number_density(
  copy_numbers,
  min_copy_number = NULL,
  max_copy_number = NULL,
  n = 512
)

Arguments

copy_numbers	a numeric vector of relative copy number values.
min_copy_number	the lower copy number value in the range of values to estimate the density.
max_copy_number	the upper copy number value in the range of values to estimate the density.
n	the number of equally-spaced points for which the density will be estimated (a smaller number may be returned if min_copy_number and/or max_copy_number are specified).

Value

a data frame with copy number and density columns

Examples

data(copy_number)
copy_number <- copy_number[copy_number$sample == "X17222", ]

density <- copy_number_density(copy_number$segmented)

density <- copy_number_density(copy_number$segmented,
                               min_copy_number = 0,
                               max_copy_number = 2.5)
