gx.quantiles

Estimate the Common Quantiles

Description

Estimates and displays the common quantiles. i.e. quartiles, quintiles, deciles, and for upper and lower extreme percentiles, for a numeric variable. For any other quantile use function gx.quantile.

Usage

gx.quantiles(x, xname = deparse(substitute(x)))

Arguments

`x`	the data set for which the quantiles are to be estimated.
`xname`	by default the character string for `x` is used for the display. An alternate title can be displayed with `xname = "text string"`, see Example.

Note

Any less than detection limit values represented by negative values, or zeros or other numeric codes representing blanks in the data, must be removed prior to executing this function, see ltdl.fix.df.

Any NAs in the data vector are removed prior to estimation.
