fc2Cond: Select probes based on fold change calculation
Description
Takes a Codelink object and calculate fold changes (M) between two conditions
(samples). Then select genes based on those who pass the passed cutoff.
Usage
fc2Cond(object, cond1=NULL, cond2=NULL, fc=1.0, verbose=FALSE)
Arguments
object
an object of class "Codelink".
cond1
numeric or character; First condition to compute M.
cond2
numeric or character; Second condition to compute M.
fc
value of the fold change cutoff
verbose
logical; if some information is printed on the console.
Details
Conditions can be passed as characters or as numeric index from the sample
slot. The intensities are internally transformed to log2 if needed. The M value
is computed as: M = cond1 - cond2
