seqdecomp

States can be represented by any substring that does not include the <code>sep</code> value. An empty separator <code>sep = ""</code> can only be used when each state is coded with a single character.

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.

seqdecomp function

<dl> <dt>data</dt>
<dd>a dataframe, 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 is <code>NULL</code>, ie all the columns. Whether the sequences are in the compressed (character strings) or extended format is automatically detected by counting the number of columns.</dd> <dt>sep</dt>
<dd>the between states/events separator used in the input data set. Default is '<code>-</code>'.</dd> <dt>miss</dt>
<dd>the symbol for missing values (if any) used in the input data set. Default is <code>NA</code>.</dd> <dt>vnames</dt>
<dd>optional names for the column/variables of the output data set. Default is <code>NULL</code>.</dd></dl>
