How to calculate the 95th percentile of a dataset?
If you want to work out the 95th percentile yourself, order the numbers from smallest to largest and find a value such that 95% of the data is below that value. R probably uses some sort of interpolation between data points. A simple approximation might be sort (data$V1) [0.95*length (data$V1)].
