seqnum {TraMineR} | R Documentation |
The function 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 0
to (nbstates-1)
.
seqnum(seqdata, with.missing=FALSE)
seqdata |
a state sequence object as defined by the |
with.missing |
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
ranging from 0
to (nbstates-1)
