[BioC] How to load annotations for pkgENTREZID, pkgGENENAME dynamically?

[Jani, Saurin D]

Dear BioC,

Here is my R script code which is running on  server in background.
##################################
chiptype <- annotation(affy_batch_object);

if(chiptype == "hu6800")
{
library(hu6800cdf);
library(hu6800probe);
library(hu6800);
library(humanCHRLOC);
library(humanLLMappings);
envGeneNames <- hu6800GENENAME; # very important
envPath2Probes <- hu6800PATH2PROBE;
envGO2AllPROBES <- hu6800GO2ALLPROBES;
envGENEIDS <- hu6800ENTREZID; # very important
}

and so on for commonly used AFFY Chips....
##################################

I have written this manually, how can I load annotations and packageENGREZID, packageGENENAME..etc. dynamically?

I am currently working with Affy chips but I also like to work on Agilent chips in futureI.

OR

I just write a perl/php scripts which prints above information...thats my thinking.

Thank you so much in advance,
Saurin
