**beadarray
**limma
**annotation data for the array (normally illuminaMousev2BeadID.db)
<pre>
source("http://www.bioconductor.org/biocLite.R")
==Annotation of Expression Sets and Fitted Data==
*To see all possible annotation criteria use:
<pre>
library(illuminaMousev2BeadID.db)
illuminaMousev2BeadID()
</pre>
*Normally you want to annotate with at least the gene symbol and gene name. Add other criteria as required
<pre>
ids = rownames(exprs(BSData))
GeneName = mget(ids, illuminaMousev2BeadIDGENENAME, ifnotfound = NA)
symbol = mget(ids, illuminaMousev2BeadIDSYMBOL, ifnotfound = NA)
anno = cbind(GeneSymbol = as.character(symbol), GeneName = as.character(GeneName))
</pre>
