is not a character, e.g. NULL, the data are not stratified.span
which controls the degree of
smoothing in the loess
function."marrayRaw"
(or possibly "marrayNorm"
), and returns a vector of fitted values to be substracted from the raw log-ratios. It calls the function maLoess
, which is not specific to microarray objects.
