uscores: Uscores for multiple columns of censored data

In NADA2: Data Analysis for Censored Environmental Data

Uscores for multiple columns of censored data

Description

Computes uscores or the ranks of uscores of censored data in the indicator format. Multiple DLs allowed.

Usage

uscores(dat.frame, paired = TRUE, rnk = TRUE)

Arguments

dat.frame	A data frame. Default format is paired = TRUE, where for 3 chemical parameters the input format is C1 I1 C2 I2 C3 I3, a concentration column followed by its corresponding indicator column.
paired	When paired = FALSE, the input format is C1 C2 C3 I1 I2 I3 where the C columns contain concentrations or a detection limit, and the I columns are their associated indicators, in the same order as the concentration columns.
rnk	A logical TRUE/FALSE variable on whether to compute the multivariate pattern on the uscores, or the ranks of the uscores. Default is rnk=TRUE, use the ranks. rnk = FALSE returns the uscores.

Value

A matrix of uscores or ranks of uscores, one column for each chemical parameter. If there is only one chemical parameter a vector of uscores or ranks of uscores is returned.

Examples

data(PbHeron)

uscores(PbHeron[,4:15])
