quantile() function in R Language is used to create sample quantiles within a data set with probability[0, 1]. Such as first quantile is at 0.25[25%], second is at 0.50[50%], and third is at 0.75[75%].
Syntax: quantile(x) Parameters: x: Data setExample 1:
# R program to create
# quantiles of a data set
# Create a data frame
d <- data.frame( name = c("Abhi", "Bhavesh", "Chaman", "Dimri"),
age = c(7, 5, 9, 16),
ht = c(46, NA, NA, 69),
school = c("yes", "yes", "no", "no") )
# Calling quantile() Function
quantile(d$age)
