This function is used for location normalization using the median of
intensity log-ratios for a group of spots. The function should be used
as an argument to the main normalization function
Name of accessor method for spot statistic used to stratify the
data, usually a layout parameter, e.g.
Name of accessor method for spot statistics, usually
A "logical" or "numeric" vector indicating the subset of points used to compute the location normalization values.
A function with bindings for the above arguments. This latter function takes as
argument an object of class
"marrayRaw" (or possibly
"marrayNorm"), and returns a vector of fitted values to be
subtracted from the raw log-ratios. It calls the function
which is not specific to microarray objects.
