Converts a vector interpreted as a classification or partitioning into a numeric vector.

partconv(x, consec=TRUE)

## Arguments

x

A vector interpreted as a classification or partitioning.

consec

Logical value indicating whether or not to consecutive class numbers should be used .

## Value

Numeric encoding of x. When consec = TRUE, the distinct values in x are numbered by the order in which they appear. When consec = FALSE, each distinct value in x is numbered by the index corresponding to its first appearance in x.

partuniq
