p2LL: A function to map from probes to unique Entrez Gene IDs
Description
For any chip, this function computes the map from unique Entrez Gene
ID to all probes.
Usage
p2LL(data)
Arguments
data
The character string naming the chip.
Value
A list, with length equal to the number of unique Entrez Gene IDs on
the chip, the elements correspond to the probes that map to the Gene ID.
Details
This function is deprecated.
This is essentially the computation of the reverse map, we store probe
to Entrez gene information in the ENTREZID environment. This is
used to compute the inverse mapping.
