gtrack.create: Creates a track from a track expression

In misha: Toolkit for Analysis of Genomic Data

Creates a track from a track expression

Description

Creates a track from a track expression.

Usage

gtrack.create(
  track = NULL,
  description = NULL,
  expr = NULL,
  iterator = NULL,
  band = NULL
)

Arguments

track	track name
description	a character string description
expr	track expression
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 creates a new track named track. The values of the track are determined by evaluation of 'expr' - a numeric track expression. The type of the new track is determined by the type of the iterator. 'Fixed bin', 'Sparse' or 'Rectangles' track can be created accordingly. 'description' is added as a track attribute.

Value

None.

Examples

gdb.init_examples()

## Creates a new track that is a sum of values from 'dense' and
## 2 * non-nan values of 'sparse' track. The new track type is
## Dense with a bin size that equals to '70'.
gtrack.create("mixed_track", "Test track",
    "dense_track +
              replace(sparse_track, is.nan(sparse_track), 0) * 2",
    iterator = 70
)
gtrack.info("mixed_track")
gtrack.rm("mixed_track", force = TRUE)
