Gene expression profiles for 189 biological samples taken from seven different tissue types.

Description

This is a subset of the data provided by the tissuesGeneExpression package available from the genomicsclass GitHub repository. The predictors are gene expression measurements from 500 genes that are a random subset of the original 22,215.

Usage

tissue_gene_expression

Format

An object of class list.

Details

The example dataset is recommended for illustrating clustering and machine learning techniques.

• x. The predictors composed of 500 genes. Each row is a gene expression profile and each column is different gene. The column names are the gene symbols.

• y. The outcomes. A character vector representing the tissue. One of seven tissue types.
