Computes uscores or the ranks of uscores of censored data in the indicator format. Multiple DLs allowed.
uscores(dat.frame, paired = TRUE, rnk = TRUE)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.
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.
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.
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.
