I'm not familiar with this database. Could you please give more 
information? Also, there are no genes measured on the GenomeWideSNP_6.0 
chip. This chip measures SNPs, which may or may not be in or near genes.

This question is too vague to be answered. What is the 'complete list'?

Maybe you are trying to subset a list or data.frame, in which case you 
should look at

?'['
?'%in%
or perhaps
?which

Best,

Jim
