## Example gene expression set

### Description

This is a matrix containing microarray gene expression values taken from a publicly available dataset (GEO ID: GSE30550; Huang Y et al. PLoS Genet 2011). This dataset contains samples from 17 patients who were exposed to Influenza and had blood drawn approximately every 8 hours for a week. Patients were classified as either symptomatic (sx) or asymptomatic (asx) based on the severity of their symptoms.

The portion of the dataset included here contains a total of 15 time points, including a pre-exposure point (time 0) and points approximately every 8 hours up to 108 hours. `eset.full` is arranged by donor, and the information for each sample is contained in a table, `flu.meta`. The metadata table contains 7 columns:

`SampleID`

  The GEO sample IDs, matching the column names of eset.full

`Subject`

  the subject ID

`Hours`

  The hour-post-infection that the sample was collected (stored as a factor)

`Hours.Numeric`

  Same as above, but stored as a numeric vector

`Condition`

  The condition of the donor, either symptomatic (sx) or asymptomatic (asx)

`Gender`

  The donor gender

`Age`

  Age of the donor at recruitment

### Usage

      eset.full
      flu.meta

### Format

`eset.full` is a matrix of gene expression measurements, with rows of genes and columns representing samples. `flu.meta` is a data frame, with rows of samples and columns of metadata information.
