Hi All,
Thanks for all comments/suggestions.
I would like to clarify a few things for some of your questions/doubts.
1) Matt Peeples' K-Clusters R scripts has covered some of pre-requisite steps
for the K-Clusters algorithm.
I would recommend for those who has not done K-Clusters to read it.
I confirm that the original problem doesn't happen in R 3.1.1. in
Windows (XP, this time). That is,

after this discussion) error.

Here is one way to use rle() to solve the problem:
shortRunsOfOnesToNAs <- function(x, n) {
r <- rle(x)
r$values[r$values==1 & r$lengths < n] <- NA
rep(r$values, r$lengths)
}
E.g.,
input <- c(0,0,1,1,1,0,0,0,0,1,1,1,1,1,1,1,1)
result <- shortRunsOfOnesToNAs(input, 5)

The function fancyRpartPlot() is actually in the rattle package, and it is
a wrapper for the prp() function in the rpart.plot package. If you look at

Hi David,
Thank you for your response.
I use png devices to create my plots. Looking at ?pdfFonts and ?Type1Font,
I believe these fonts only apply to pdf devices. Additionally, ?grid::gpar
and ?png are not specific about default font options.
Any suggestions?
