arrayBGcorr(x, ...)

## S4 method for signature 'MultiSet'
arrayBGcorr(x, method = "none", offset = 1,
  transform = "log2", ...)

Arguments

x

MultiSet object with fMedian and bMedian matrices in the assayData slot

method

Character string specifying background correction method. Valid methods are 'none', 'subtract', 'edwards', ratio' or 'normexp'. Defaults to 'none' if no method is specified.

offset

numeric value added to raw signal intensity before background correction is implemented

transform

Expression to transform raw data. Defaults to log2

Value

MultiSet object with transformed and background corrected foreground signal in the fMedian matrix
