modNormalize
normalizes feature data.
modNormalize(object, MARGIN = c(1, 2), plotSkip = TRUE)# S4 method for ExprsArray
modNormalize(object, MARGIN = c(1, 2),
plotSkip = TRUE)
Specifies the ExprsArray
object to undergo pre-processing.
A numeric vector. The margin by which to normalize.
Provide MARGIN = 1
to normalize the feature vector.
Provide MARGIN = 2
to normalize the subject vector.
Provide MARGIN = c(1, 2)
to normalize by the subject vector
and then by the feature vector.
A logical scalar. Toggles whether to produce side-by-side plots
of the before and after ExprsArray
summary.
A pre-processed ExprsArray
object.
ExprsArray
: Method to normalize an ExprsArray
object.
This method normalizes subject and/or feature vectors according to the
formula y = (x - mean(x)) / sd(x)
.
