Examples

data(famform)
famform.seq <- seqdef(famform)

seqmpos(famform.seq[1,],famform.seq[2,])
seqmpos(famform.seq[2,],famform.seq[4,])

## Example with gaps in sequences
a <- c(NA,"A",NA,"B","C")
b <- c(NA,"C",NA,"B","C")

ex1.seq <- seqdef(rbind(a,b))

seqmpos(ex1.seq[1,], ex1.seq[2,])
seqmpos(ex1.seq[1,], ex1.seq[2,], with.missing=TRUE)
