seqconc: Concatenate vectors of states or events into a character string

Description

Concatenate vectors of states or events into a character string. In the string, each state is separated by 'sep'. The void elements in the input sequences are eliminated.

Usage

seqconc(data, var=NULL, sep="-", vname="Sequence", void=NA)

Value

a vector of character strings, one for each row in the input data.

Arguments

data

A data frame or matrix containing sequence data (tibble will be converted with as.data.frame).

var

List of the columns containing the sequences. Default is NULL in which case all columns are retained. Whether the sequences are in the compressed (character strings) or extended format is automatically detected by counting the number of columns.

sep

Character used as separator. By default, "-".

vname

an optional name for the variable containing the sequences. By default, "Sequence".

void

the code used for void elements appearing in the sequences (see Gabadinho et al. (2009) for more details on missing values and void elements in sequences). Default is NA.
