Calculates probe affinities from sequence.
Adapted from compute.affinities in the gcrma package.
Attempts to find the tab-separated probe sequence file associated with
a particular CDF, and matches sequence to probe index in order to assign
an affinity to each probe.
# S3 method for AffymetrixCdfFile
computeAffinities(this, safe=TRUE, force=FALSE, verbose=FALSE, ...)Returns a numeric
vector of (log2) probe affinities, of length equal
to the total number of features on the array.
