fc2Cond: Select probes based on fold change calculation
In codelink: Manipulation of Codelink microarray data

Description Usage Arguments Details Value Author(s)

Takes a Codelink object and calculate fold changes (M) between two conditions (samples). Then select genes based on those who pass the passed cutoff.

1	fc2Cond(object, cond1=NULL, cond2=NULL, fc=1.0, verbose=FALSE)

`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.

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

A logical vector indicating which genes pass the cutoff
