Resolve a Position to Three Identifying Words
Description
from_position takes latitude/longitude pair (or sequence of them) and
resolves them to a word cluster used by what3words.
Usage
from_position(key, positions, ...)
Arguments
key |
an API key obtained from what3words. |
positions |
either a vector containing a single latitude/longitude pair, or a list of vectors for vectorised operations. |
... |
further arguments to pass to httr's GET. |
Value
A list containing the words, positions and language of those words.
See Also
from_position for the opposite operation.
Examples
## Not run:
# Ask for a single set of words from the what3words API (note: this requires an API key.
# Don't actually use 'ANAPIKEY'.)
results <- from_position(key = "ANAPIKEY", positions = c(6.385336,-36.293769))
## End(Not run)
Resolve Three Identifying Words to a Position
Description

converts them back into latitude/longitude pairs.
Usage
from_words(key, words, ...)
Arguments
key |
an API key obtained from what3words. |
words |
either a vector of words, for a single latitude/longitude pair, or a list of vectors for vectorised operations. |
... |
further arguments to pass to httr's GET. |
Value
A list containing the words, positions and language of those words.
See Also
from_position for the opposite operation.
Examples
## Not run:
