Better check for keywords

[hadley]

From Kurt Hornik:

Package CoFRA has CoFRA.R with

#' @keywords heatmap
#' library(CoFRA)
#' data(iBAQ)
#' Fac=factor(c("MCCTT","MCCTT","MCCTT","MCCT","MCCT","MCCT","MC","MC","MC","MCT","MCT","MCT","MTT","MTT",
#' "MTT","MT","MT","MT","sN","sN","sN","sNT","sNT","sNT","iN","iN","iN","iNT","iNT","iNT"))
#' dfComp=data.frame(Con=c("MCCT","MT","MC","iN","sN","AllC,MCCT,MT,MC,iN,sN"),Tre=c("MCCTT","MTT",
#' "MCT","iNT","sNT","AllT,MCCTT,MTT,MCT,iNT,sNT"))

Probably safe to check that keywords fit on one line.
