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 missing values (NA's) are eliminated in the input sequences.
Usage
seqconc(data, var=NULL, sep="-",vname="Sequence")
Arguments
data
a dataframe or matrix containing sequence data.
var
the list of columns containing the sequences. Defaut to 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 character used as separator. By default, "-".
vname
an optional name for the variable containing the sequences. By default, "Sequence".
Value
a vector of character strings, one for each row in the input data.
