I am new to R and have written a function that clusters on subsets of a big data data set with 60,000 points.  I am not sure why, but I keep getting a run-time error.  Any suggestions would be greatly appreciated.

Here is the code:

library(cba)

d<-read.csv("data.csv", header=TRUE)

v<-c(53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,21,72 73,74,75,76,77,78)

clusterMe<-function(d,v){
	tempMat<-subset(d,d[,v[1]]=="TRUE")
	rc<-rockCluster(tempMat,n=5,theta=.2)
	tempMat<-cbind(tempMat,rc$cl)
	M<-tempMat
	for (i in 2:26){
		tempMat<-subset(d,d[,v[i]]=="TRUE")
		rc<-rockCluster(tempMat,n=5,theta=.2)
		tempMat<-cbind(tempMat,rc$cl)
		M<-rbind(M,tempMat)
	}
	M
}

clusters<-clusterMe(d,v)
