## annot.chr21: Annotation information for chromosome 21, hg38 genome

### Description

This is the annotation information returned from `getAnnot`, subsetted for chromosome 21 for convenience in running the examples. The annotation is obtained using the `annotatr` package.

### Usage

    data(annot.chr21)

### Format

a `GRangesList` object with two elements returned by `getAnnot`. The first contains CpG category information in the first element (optional) coding gene sequence information in the second element (optional). At least one of these elements needs to be non-null in order for any annotation to be plotted, but it is not necessary to contain both.

### Source

Obtained from running `annoTrack` function and then subsetting the results to only include chromosome 21. A script which executes these steps and constructs the `annot.chr21` object may be found in ‘inst/scripts/get_annot.chr21.R’

### Examples

    data(annot.chr21)
