transeS {LMGene} | R Documentation |
For each element in the array of expression data, this applies the glog transform y -> glog (y-alpha, lambda). If alpha is a vector, it must have one entry per sample, and transeS will use the appropriate entry from the vector.
transeS(eS, lambda, alpha)
eS |
An unprocessed expression set. |
lambda |
The parameter lambda to be used in the glog transform (Durbin and Rocke 2003). |
alpha |
The alpha parameter(s) for the glog transform. May be a single number used for all samples, or a vector with one entry per sample. |
Returns an expression set with the same vlist as eS, but the matrix is now glog-transformed. That matrix can be normalized with norm
or lnorm
.
