How to Calculate Percentiles in R. We can easily calculate percentiles in R using the quantile function, which uses the following syntax: quantile (x, probs = seq (0, 1, 0.25)) where: x: a numeric vector whose percentiles we wish to find. probs: a numeric vector of probabilities in [0,1] that represent the percentiles we wish to find.An IQ score equal to 95 corresponds to the 95th percentile rank, indicating that 95% of the population has an IQ score equal to or lower than 95.
