## 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)

### Arguments

`data` | A dataframe or matrix containing sequence data.
`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`.

### Value

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