Returns the state frequencies (total durations) for each sequence in the sequence object.
seqistatd(seqdata, with.missing=FALSE, prop=FALSE)
a sequence object (see seqdef function).
logical: if set as TRUE, total durations are also computed for the missing status (gaps in the sequences). See seqdef on options for handling missing values when creating sequence objects.
logical: if TRUE, proportions of time spent in each state are returned instead of absolute values. This option is specially useful when sequences contain missing states, since the sum of the state durations may not be the same for all sequences.

data(actcal)
actcal.seq <- seqdef(actcal,13:24)
seqistatd(actcal.seq[1:10,])
## Example using "with.missing" argument
data(ex1)
ex1.seq <- seqdef(ex1, 1:13, weights=ex1$weights)
seqistatd(ex1.seq)
seqistatd(ex1.seq, with.missing=TRUE)
