Recodes sequence data into the shape used for qualitative harmonic analysis.

Usage

seq2qha(seqdata, periods)

Arguments

seqdata	a sequence object (see seqdef function).
periods	numeric vector of the first positions of the periods used for recoding

Value

A data frame with one column by combination of period and state (i.e. number of columns = number of periods * number of states in the alphabet).
