combine {matchprobes} | R Documentation |
The function takes two AffyBatches and their respective probe sequence information and merges the intensities from the matching probes only into one AffyBatch.
combine(batch, probepkg, newcdf, verbose=TRUE)
batch |
A list of two AffyBatches. |
probepkg |
A character vector of length 2, containing the names
of the probe sequences libraries (for example, hgu133aprobe )
that go with the AffyBatches. |
newcdf |
The name of the name CDF environment that is to be created. |
verbose |
If TRUE, messages are printed to the console. |
This function is EXPERIMENTAL; no guarantee that the resulting data makes biological sense.
You may want to have a look at the code of this function and at intermediate results.
Presently the code is written for two chiptypes, but if necessary can
now be easily generalized to n
>=2.
A list with two elements: dat
, an AffyBatch
, and
cdf
, an environment, which contains a "CDF" probe-set to probe
mapping (as for ordinary genechips).
cdf is obtrained by restricting the probe-set to probe of the
second batch
and probelib
.
A vignette is being written.
