How to get latitude coordinates to state code?
If you need higher resolution state boundaries, read in your own vector data as an sf object using sf::st_read () or by some other means. One nice option is to install the rnaturalearth package and use it to load a state vector layer from rnaturalearthhires. Then use the lonlat_to_state () function we just defined as shown here:
How to find longitude and latitude for list of regions or country?
To install it type the below command in the terminal. Example: Let’s create a pandas dataframe containing a list of regions or countries. Now Let’s find the latitude and longitude of the following regions or countries. Showing the output produced as dataframe.

How to find the closest neighbor after calculating distance?
For obtaining the closest neighbor after calculating distance, you can use sort () with the partial = 2 argument. Depending on the amount of data, this could be much faster than using order as in the previous solution.
How to find the distance between two ponds?
All my coordinates are in latitude and longitude I want to put the name of the nearest neighboring pond in the column neighbor, its lat and long in n.lat and n.long, the distance between the two ponds in n.distance, and the area, canopy and avg.depth in each of the appropriate columns.
How to find the smallest distance between two points?
You create a mega-grid of every single possible combination of lat/lons, then you can find the one that has the smallest distance using geosphere. The example is where you have two datasets with different points to compare – but you can adjust it easily by duplicating the first dataset.
