## RNA-seq data matrix from ProteinAtlas project

### Description

`VALexp` is a gene expression data matrix with rows (369 genes) and 35 columns (samples from 7 tissue types). This data matrix was obtained from EBI arrayexpress and is part of ProteinAtlas project. It is a very big dataset, so we only used a small subset as an example dataset here.

    data("VALexp")

### Format

The format is: num [1:467, 1:200] 0 2.379 0 0.379 5.392 ... - attr(*, "dimnames")=List of 2 ..$ : chr [1:467] "9496" "22797" "7080" "6943" ... ..$ : chr [1:200] "saliva-secreting gland" "lung" "liver" "heart" ...
