Description

Toy data set consisting of promoter regions of 150 random genes from the human chromosome 22

Usage

ch22Promoters

Arguments

format

A character vector of length 150. Each string is a nucleotide sequence that corresponds to the promoter region of a gene from the human chromosome no. 22 (according to the human genome assembly hg18). The sequences start 999 bases upstream of the transcription start site (TSS) and end with the TSS itself. The names attribute contains the RefSeq IDs of the genes.

Examples

Run this code
## load data set
data(ch22Promoters)

## display names of first five samples
names(ch22Promoters)[1:5]

## display last 50 bases of the first five samples
substr(ch22Promoters[1:5], 951, 1000)
