seq_sim | R Documentation |
Compute similarity scores between sequences of integers
seq_sim( a, b, method = c("osa", "lv", "dl", "hamming", "lcs", "qgram", "cosine", "jaccard", "jw"), q = 1, ... )
a |
|
b |
|
method |
Method for distance calculation. The default is |
q |
Size of the q-gram; must be nonnegative. Only applies to
|
... |
additional arguments are passed on to |
A numeric
vector of length max(length(a),length(b))
. If one of the
entries in a
or b
is NA_integer_
, all comparisons with that
element result in NA
. Missings occurring within the sequences are treated
as an ordinary number (the representation of NA_integer_
).
