Hi Ravi,

You can change the levels in a factor by using factor() and mention explicitly the order of levels in a vector.

Use statement like below,

feedback = c("Good","OK","Can be Better","Very Bad")

order = factor(feedback, levels = c("Good","OK","Can be Better", "Very Bad"))

print(order)

Hope it helps!

You can also use relevel() to change the level in a factor.

relevel() takes the factor and the level element and push it to front in the level.

write as below - 

feedback = c("Good","OK","Can be Better","Very Bad")
rating = factor(feedback)
print(rating)
print(as.integer(rating))
rating = relevel(rating,"Can be Better")
rating = relevel(rating,"OK")
rating = relevel(rating,"Good")
print(rating)
print(as.integer(rating))
