seqstatl

Returns a list containing distinct states or events found in a data frame or matrix containing sequence data, the alphabet.

Data handling

Set of sequence analysis tools for manipulating, describing and rendering categorical sequences, and more generally mining sequence data in the field of social sciences. Although this sequence analysis package is primarily intended for state or event sequences that describe time use or life courses such as family formation histories or professional careers, its features also apply to many other kinds of categorical sequence data. It accepts many different sequence representations as input and provides tools for converting sequences from one format to another. It offers several functions for describing and rendering sequences, for computing distances between sequences with different metrics (among which optimal matching), original dissimilarity-based analysis tools, and functions for extracting the most frequent event subsequences and identifying the most discriminating ones among them. A user's guide can be found on the TraMineR web page.

seqstatl function

<dl> <dt>data</dt>
<dd>a data frame, matrix, or character string vector containing sequence data (tibble will be converted with <code>as.data.frame</code>).</dd> <dt>var</dt>
<dd>the list of columns containing the sequences. Default <code>NULL</code> means all columns. Whether the sequences are in the compressed (character strings) or extended format is automatically detected from the number of columns.</dd>
</dl>
.
<dl>
 <dt>format</dt>
<dd>the format of the sequence data set. One of <code>"STS"</code>, <code>"SPS"</code>, <code>"DSS"</code>. Default is <code>"STS"</code>. The <code>seqstatl</code> function uses the <code>seqformat</code> function to translate between formats when necessary.</dd></dl>
