seqmpos: Number of matching positions between two sequences.

In TraMineR: Trajectory Miner: a Sequence Analysis Toolkit

Number of matching positions between two sequences.

Description

Returns the number of common elements, i.e., same states appearing at the same position in the two sequences.

Usage

 seqmpos(seq1, seq2, with.missing=FALSE)

Arguments

seq1	a sequence from a sequence object.
seq2	a sequence from a sequence object.
with.missing	if TRUE, gaps appearing at the same position in both sequences are also considered as common elements

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)
