Sometimes you have to cut your histogram at some value but you want to still inform the reader how many values you cut off. Here I simply add one additional histogram bar at the right hand side, ">30", to display the missing values.
data(USArrests, "VADeaths")
data <- USArrests$Rape
h <- hist(data, breaks=seq(0,3000,1), plot=F)
subset <- h$counts[seq(1,limit)]
rest <- sum(h$counts[seq(limit+1,length(h$counts))])
data <- c(subset, rest)
labels <- c(seq(1,limit,1),paste(">",toString(limit), seq=""))
