gx.quantile: Estimate the Quantile for a Specified Fractile

Description

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

Usage

gx.quantile(xx, f, display = TRUE)

Arguments

xx

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

f

the fractile for which the quantile is required, must be in the range zero to 1.

display

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

Value

q

the estimated quantile.
