R help - Aug 2012 - Filtering Beadarray Summary Data

Hey all,

I was wondering if someone could tell me a way to remove the lines in my
annoated BeadSummary Data file that have a PROBEQUALITY of "BAD" and
"Match".

They method they used in the Bead summary tutorial gives me the following
error. 
Anyone have any ideas?

Thanks in advance
Will

ids <- as.character(featureNames(BSData.norm)) 
qual <- unlist(mget(ids, illuminaHumanv4PROBEQUALITY, ifnotfound = NA))
table(qual)
  Bad        Good     Good***    Good****    No match     Perfect
      12376        1158         137         507         468       27335
 Perfect*** Perfect****
       2911        2394

rem <- qual == "No match" | qual == "Bad" | is.na(qual)
BSData.filt <- BSData.norm[!rem, ]

I get the following error

Error in FUN(X[[2L]], ...) : (subscript) logical subscript too long
