Hi @pratibha12,
The cut() function can do what you require. You can also set your own breakpoints, if preferred.

# make some dummy data
birthwt <- rnorm(20, 3.0, 0.5)
birthwt

cut(birthwt, breaks=4,
    labels=c("small","medium",
	      "large","very_large"))
help(cut)

<=500 = extremly low
501-1000 = low
1001- 1500= average

1500 = normal

Some ‘ifelse’ functions should do.
