RAPI

How to use

```{r installation, eval = FALSE} devtools::install_github("nourqweder/RAPI", build_vignettes = TRUE)

## Introduction
Before start using this package, `ggmap` and `leaflet` package must be installed in order to plot the result of modelling. This packages is created to provide connection between the Google Geocoding API and the users, so that geo-coordinates can be transformed to address, and address can be transformed to geo-cordinates for more efficient detecting position.  With package `leaflet`, the map is drawn, and a few different display mode can be selected.


```{r, eval = FALSE}
#  https://maps.googleapis.com/maps/api/geocode/json?parameters

As above mentioned, RAPI works as a linker between the users and the Google Geocoding API.

Usage Methods

geocodeBylatlng

geocodeBylatlng(latitude, longitude) This function is used to find a written address with its' latitude and longitude. Using this function connects user to the Google API; Google API responds by providing where the input geo-coordinates corresponds to. Input values must be characters.

Followings are examples:

geocodeBylatlng("37.56654, 126.978")

geocodeBylatlng("37.55723, 127.0453")

getAdressInfoByLocation

getAdressInfoByLocation(location) This function is used to find a geo-coords, which are latitude and longitude of the user-given location. Using this function connects user to the Google API; Google API responds by providing where the input location corresponds to. Input values must be character value.

Followings are examples:

getAddressInfoByLocation("Mjölby")

getAddressInfoByLocation("Damascus University")

getInforFromInput

getInforFromInput(address) This function produces data frame that contains latitude, longitude, and written address of the user-given address. This function contains getAdressInfoByLocation() in it; putting written address in the function will generate geo-coords as embedded function within this has connection to Google API to detect its latitude and longitude. Input values must be character values.

Following is an example:

getInforFromInput(c("Spain", "smålandsvägen 42D, Linghem"))

getDataFromCSV

getDataFromCSV(file path) This function reads data from csv file that contains location and/or geo-coordinate information. Once the data is read, it is passed to getInforFromInputIf function; a data frame with address, latitude and longitude is returned as user-input csv data is sent to Google API.

Following is an example:

getDataFromSCV(./example.csv)
