standardise2 {Mfuzz} | R Documentation |
Standardisation of the expression values of every gene is performed, so that the expression values at a chosen time point are zero and the standard deviations are one.
standardise2(eset,timepoint=1)
eset |
object of the class ExpressionSet. |
timepoint |
integer: which time point should have expression values of zero. |
The function produces an object of the ExpressionSet class with standardised expression values.
