Calculating quantiles in R

0 votes

How can the quantile be calculated? I tried the below formula:

quantile = p*(n+1) 

  • here 'p' is the percentage 
  • 'n' is the number of rows in a dataset
However, this doesn't seem to work.

You can follow this code:

y <- rnorm(100) #input data
quantile(y) 
quantile(y, c(0.1, 0.9))  # 10th and 90th centiles
