This function performs transformation of phylostratum values.
tfPS(ExpressionSet, transform)
ExpressionSet |
a standard PhyloExpressionSet object. |
transform |
a character vector of any valid function that transforms PS values. Possible values can be:
|
This function transforms the phylostratum assignment.
The return value of this function is a PhyloExpressionSet object with
transformed phylostratum tfPhylostratum
as the first column, satisfying
is.ExpressionSet
. Note that the input transform
must be an
available function, currently limited to only "qr"
(or "quantilerank"
).
a standard PhloExpressionSet object storing transformed Phylostratum levels.
