A generic function to extract the background data for micro array data.

extract_bg(iden, data_files, genepix_vars = genepix_vars)

Arguments

iden

A character indicating the name of the object to be used under data_files.

data_files

A list of data objects with names utilised by iden.

genepix_vars

A list of specific definitions of the experiment design. See array_vars.

Value

A data frame of background values

Details

Extract the background values
