y_probes: Y chromosome probe list

In SamBuckberry/massiR: massiR: MicroArray Sample Sex Identifier

Description

A list containing probes corresponding to y chromosome genes for Illumina and Affymetrix platforms. Each item in the list is a data.frame of y chromosome probes that can be used in the massi analysis. The names of each item in the list correspond to the ensembl biomart attribute names.

Usage

data(y.probes)

Format

The format is: List of 6 $ illumina_humanwg_6_v1:'data.frame': 58 obs. of 0 variables $ illumina_humanwg_6_v2:'data.frame': 74 obs. of 0 variables $ illumina_humanwg_6_v1:'data.frame': 112 obs. of 0 variables $ illumina_humanht_12 :'data.frame': 112 obs. of 0 variables $ affy_hugene_1_0_st_v1:'data.frame': 138 obs. of 0 variables $ affy_hg_u133_plus_2 :'data.frame': 94 obs. of 0 variables

Details

The y chromosome probes for each platform were downloaded from Ensembl biomart using the 'biomaRt' package. For more details on the methods of selecting the probes and how to obtain probes for other platform, see the vignette for the massiR package.

Examples

# load the probes list
data(y.probes)
# look at the platform names
names(y.probes)
# extract the probes using the platform name
probe.list <- y.probes[["illumina_humanwg_6_v2"]]
