gx.fractile: Estimate the Fractile for a Specified Quantile

Description

Estimates the fractile for a specified quantile of a data set by linear interpolation from the ranked data. If the function is run as temp <- gx.fractile(xx, q) the fractile is not displayed, but retained in temp for subsequent use or display.

Usage

gx.fractile(xx, q, display = TRUE)

Arguments

xx

the data set for which the quantile is to be estimated.

q

the fractile (value) for which the quantile is required, must be within the range of xx.

display

the default is to display the quantile and estimated fractile on the current device. If no display is required, set display = FALSE.

Value

f

the estimated fractile.
