pre.processing: Normalize the data before the classification step.
Description
n0 - without normalization
n1 - standardization ((x-mean)/sd)
n2 - positional standardization ((x-median)/mad)
n3 - unitization ((x-mean)/range)
n4 - unitization with zero minimum ((x-min)/range)
n5 - normalization in range <-1,1> ((x-mean)/max(abs(x-mean)))
Usage
pre.processing(OPs, NOPs, POPs, DOPs, type = "n0", verbose = TRUE, ...)
Arguments
OPs
Data table including the confirmed operon pairs (OPs). See select.ops
.
POPs
Data table including gene pairs with an operon status to (re)define (POPs). See select.pops
.
DOPs
Data table including the operon pairs annotated in DOOR database (DOPs). See select.ops.indoor
.
type
Charcater vector indicating the method to use for the normalization step. Default value is "n0".
verbose
Default logical value is TRUE.
OPs
Data table including the confirmed non-operon pairs (NOPs). See select.nops
