tissue_example: Example gene expression dataset
Description
tissue_example
is a dataset extracted from Lukk et al, it contains a subset of 24 samples
from more than 5000 in the original article. The gene expression in all the samples is measured using
Affymetrix U133A array.
The dataset is a list with 2 slots
-
exp
- expression matrix;
-
annot
- annotation data frame.
Details
The GOsummaries objects based on this data created in different examples are alaso attached to the
package. These can be used to test the package if no internet connection is available. Names of these are gs_kmeans
, gs_limma
, gs_limma_exp
and gs_pca
