citygeocoder::reverse_geocode(lon = -98.7654321, lat = 34.56789)
#>        city state       lon      lat  distance

3. Batch Mode!

df1 <-
  read.table(
    text =
    "City       | State
    Scranton    | PA
    Oakland     | CA
    New York    | NY
    Columbus    | IN",
    header = T,
    sep = "|",
    stringsAsFactors = FALSE,
    strip.white = TRUE
  )

citygeocoder::geocode(df1$City, df1$State)
#>          lon      lat
#> 1  -75.66241 41.40897
#> 2 -122.27080 37.80437
