seqetm {TraMineR} | R Documentation |
This function automatically create an event transition matrix to transform state sequences data in TSE format (transitions).
seqetm(seq, method = "transition", use.labels = TRUE, sep = ">", bp = "", ep = "end")
seq |
The state sequence to create transitions from |
method |
The method to use. Actually, "transition","state" and "period" are available. |
use.labels |
If true, transitions names are build from sequence labels instead of sequence alphabet. |
sep |
Separator to use between period in "transition" method. |
bp |
Prefix to signal begining of a period |
ep |
Prefix to signal end of a period |
Three methods are implemented and can be set through the method parameter: 'transition' automaticaly generates a distinct event for each transition and the begining of the sequence; 'state' generates one event per state, in order to analyse state sequence using event sequences methods; 'period' automaticaly generates two events for each transition: one for the end of the previous period, and the other one for the beginning of the new period.
The event matrix.
See Also seqformat
for conversion to TSE format and seqecreate
for handling transition data.
