[R] Package "maps": what is the name of county # 2395?

[Dimitri Liakhovitski]

I am using "maps". I am running the following code to get this list of
all the counties:

map('county', plot=FALSE)$names

In the output, all counties have first the state listed and then,
after a comma, the name of the county.

However, county # 2395 (State = south dakota) has no county name.
Anyone knows what this county is?

Thank you!
