gsample: Returns samples from the values of track expression

In misha: Toolkit for Analysis of Genomic Data

Returns samples from the values of track expression

Description

Returns a sample of the specified size from the values of track expression.

Usage

gsample(expr = NULL, n = NULL, intervals = NULL, iterator = NULL, band = NULL)

Arguments

expr	track expression
n	a number of items to choose
intervals	genomic scope for which the function is applied
iterator	track expression iterator. If 'NULL' iterator is determined implicitly based on track expression.
band	track expression band. If 'NULL' no band is used.

Details

This function returns a sample of the specified size from the values of track expression. If 'n' is less than the total number of values, the data is randomly sampled. Call set.seed() before this function to make the sample reproducible.

If 'n' is higher than the total number of values, all values are returned (yet reshuffled).

Value

An array that represent quantiles.
