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 ma2D
, which is not specific to microarray objects.
z
is regressed on spot row and column coordinates, separately within print-tip-group, using the loess
function.
