GeneSelector (version 2.22.0)

toydata: Simulated gene expression dataset.

Description

A matrix with rows corresponding to genes and colums corresponding to observations (arrays). The first row contains the class labels (1 and 2), the following 2000 rows the gene expressions. The gene expressions were drawn from a multivariate normal distribution of dimension 2000 with mean vector zero and an unstructured simulated covariance matrix drawn from an inverse Wishart distribution. The first 40 genes are differentially expressed, the differences in the mean for the first class were drawn from a normal distribution.

Usage

data(toydata)

Examples

data(toydata)
## extract class labels
yy <- toydata[1,]
table(yy)
## extract gene expressions
xx <- toydata[-1,]
