# Example 1

library(iemisc)

lat_long2state(latitude = c(36.3684553, 40), longitude = c(-82.1796880, -89))
lat_long2state(latitude = "36.3684553", longitude = "-82.1796880")



# Example 2

# Test the function using points in Wisconsin and Oregon (From Source 1)

library(iemisc)

x = c(-90, -120); y = c(44, 44)
lat_long2state(latitude = y, longitude = x)
