The agrep function in base R also returns a Levenshtein distance.

Subject: [R] Pattern names matching
Dear R magic guys.. I have two tables (actually will be dataframes),
both
with names to be matched.
The names on the first dataframe are from a study with antenatal
visits on
some health centers here. It happens that we need the delivery info.
And
half and some thing else of the women decided to delivery some where
else
our health units. We managed to get the names from some other places
but now
we have to match our 4000 original names with over 20000 other names.
To make thing more bitter some names have badly written. So I need
some
algorithm like Levenstein or sondex or phonix or something better
already on
R. Can you help me?
