Sequence length

Description

Returns the length of sequences.

Usage

seqlength(seqdata, with.missing=TRUE)

Arguments

seqdata

a sequence object created with the seqdef function.
with.missing

logical: should non-void missing values be treated as a regular state? Default is TRUE. If FALSE missing values are considered as void.

Details

The length of a sequence is computed by counting its number of non void elements, i.e. including non-void missing values. The seqlength function returns a vector containing the length of each sequence in the provided sequence object.
