In misha: Toolkit for Analysis of Genomic Data

Creates a 'Sparse' track from intervals and values

Description

Creates a 'Sparse' track from intervals and values.

Usage

gtrack.create_sparse(
  track = NULL,
  description = NULL,
  intervals = NULL,
  values = NULL
)

Arguments

track	track name
description	a character string description
intervals	a set of one-dimensional intervals
values	an array of numeric values - one for each interval

Details

This function creates a new 'Sparse' track with values at given intervals. 'description' is added as a track attribute.

When multiple databases are connected via gsetroot, the track is created in the current working directory (.misha$GWD), which defaults to the last connected database. Use gdir.cd with an absolute path to change where new tracks are created.

Value

None.
