I am using the following command:

> plot(DBdata,cexRow=2,cexCol=2,dendrogram='none',lhei = c(0.5,6),lwid = c(0.5,4),
ColAttributes=c(DBA_TREATMENT,DBA_CONDITION),key=F,
colSideCols=list(c("lightpink","skyblue"),c("chocolate","darkgrey","darkorchid4")))

but unable to control the font size for the ColAttributes in the annotation bar. Any help or suggestion will be highly appreciated.
