Hi all
I'm trying to match a numeric code to a vector of numeric codes:
a <- c(12345, 12346, 12347)
agrep(12349, a, max.distance=list(substitutions=1))
# [1] 1 2 3
agrep(12399, a, max.distance=list(substitutions=2))
# integer(0)
I didn't expect the latter result as substituting two characters from
the pattern makes the pattern identical to the vector elements.
What do I need to change to match with more than 1 substitution allowed?
Thanks in advance,
Nik
