readin {affycomp} | R Documentation |
Reads a comma-delimited file containing the expression values of the
dilution and spike-in data sets and creates a ExpressionSet
read.dilution(filename) read.spikein(filename,cdfName=c("hgu95a","hgu133a"),remove.xhyb=TRUE) read.newspikein(filename)
filename |
character containing the filename to be read. |
cdfName |
are we reading data from the hgu95a or hgu133a spike-in experiment? |
remove.xhyb |
logical. If TRUE possible cross hybridizers
are removed from the HGU133A spikein. See remove.hgu133a.xhyb . |
The file to be read must be comma-delimited with the first row
containing the cel filenames (case sensitive). The first column must
be the Affymetrix gene identifiers. read.dilution
will put
things in the right place.
read.newspikein
is a wrapper to read results from the hgu133a
spikein experiment.
