Transform into a sequence object with numerical alphabet.
seqnum transforms the provided state sequence object into an equivalent sequence object in which the original alphabet is replaced with an alphabet of numbers ranging from
a state sequence object as defined by the
logical: Should missing elements in the sequences be turned into numerical values as well? The code for missing values in the sequences is retrieved from the
The first state (for example
'A') is coded with the value
0, the second state (for example
'B') is coded with the value
1, etc... The function returns a sequence object containing the original sequences coded with the new numerical alphabet
1 2 3 4 5 6 7 8 9 10 11 12 13 14
data(actcal) actcal.seq <- seqdef(actcal,13:24) ## The first 10 sequences in the actcal.seq ## sequence object actcal.seq[1:10,] alphabet(actcal.seq) ## The first 10 sequences in the actcal.seq ## sequence object with numerical alphabet seqnum(actcal.seq[1:10,]) ## states A,B,C,D are now coded 0,1,2,3 alphabet(seqnum(actcal.seq))
