Question

How can I find the percentile rank of a value in R?

Answer 1

To find the percentile rank of a value in R, you can use the ecdf() function. 

Here's an example:

# Example data
data <- c(10, 20, 30, 40, 50, 60, 70, 80, 90, 100)

# Calculate the percentile rank of a value
value <- 35
percentile_rank <- ecdf(data)(value) * 100

# Print the result
print(percentile_rank)
 

In this code, the ecdf() function creates an empirical cumulative distribution function from the data vector. Then, by passing a specific value to this function and multiplying the result by 100, you obtain the percentile rank of that value.
