This document indicates the different data-sets included in brgedata. The description includes the technology used to create the and the number of samples and features in each one.
brgedata 1.32.0
brgedata includes a collection of BRGE omic and exposome data from the same cohort. The diferent objects guarantees a minimum of samples in common between all sets.
Data available in this R package:
| Data Type | Number of Samples | Number of Features | Technology | Object Name | Class |
|---|---|---|---|---|---|
| Exposome | 110 | 15 | brge_expo |
ExposomeSet |
|
| Transcriptome | 75 | 67528 | Affymetrix HTA 2.0 | brge_gexp |
ExpressionSet |
| Methylome | 20 | 392277 | Illumina Human Methylation 450K | brge_methy |
GenomicRatioSet |
| Proteome | 90 | 47 | brge_prot |
ExpressionSet |
sex and age was included as phenotipic data in each set. Moreover, the ExposomeSet includes asthma status and rhinitis status of each sample.
To load the exposome data, stored in an ExposomeSet, run the follow commands:
data("brge_expo", package = "brgedata")
