Example gene expression set
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:
The GEO sample IDs, matching the column names of eset.full
the subject ID
The hour-post-infection that the sample was collected (stored as a factor)
Same as above, but stored as a numeric vector
The condition of the donor, either symptomatic (sx) or asymptomatic (asx)
The donor gender
Age of the donor at recruitment
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.
