seqdecomp: Convert a character string into a vector of states or events

In TraMineR: Trajectory Miner: a Sequence Analysis Toolkit

Convert a character string into a vector of states or events

Description

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

Usage

 seqdecomp(data, var=NULL, sep='-', miss="NA", vnames=NULL)

Arguments

data	a dataframe, matrix, or character string vector containing sequence data (tibble will be converted with as.data.frame).
var	the list of columns containing the sequences. Default is NULL, 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.
sep	the between states/events separator used in the input data set. Default is '-'.
miss	the symbol for missing values (if any) used in the input data set. Default is NA.
vnames	optional names for the column/variables of the output data set. Default is NULL.

# 2 sequences of length 6
seqdecomp(c("ABBCDD","BBCCAD"),sep="")
