climate: Returns temperature, dew temperature, pressure, wind bearing...

In Bolshom/optimumtt: A colection of functions to help cyclists.

Description

Using the package "darksky" it's possible to get those weather reports.

Usage

climate(Ta, La, date)

Arguments

Ta	Latitude of a given location.
La	Longitude of a given location.
date	Date and time to get the weather report. Check example for input format.

Details

To use the package "darksky" to collect weather report, you must activate the API with your key. Check https://darksky.net/dev for more info.

Value

c2	It's a vector containing:
c2[1]	Temperature in Celsius.
c2[2]	Dew temperature in Celsius.
c2[3]	Air pressure in hPa.
c2[4]	Wind bearing on 0<c2><ba>-360<c2><ba> scale. 0<c2><ba> means a wind blowing from North to South, 90<c2><ba> means East to West, 180<c2><ba> means South to North and, finally, 270<c2><ba> is West to East.
c2[5]	Wind speed in m/s.

{
    require(darksky)
    require(weathermetrics)
    c1 = darksky::get_forecast_for(Ta, La, date)
    c2 = 0
    c2[1] = weathermetrics::fahrenheit.to.celsius(c1$currently$temperature,
        2)
    c2[2] = weathermetrics::fahrenheit.to.celsius(c1$currently$dewPoint,
        2)
    c2[3] = c1$currently$pressure
    c2[4] = c1$currently$windBearing
    c2[5] = c1$currently$windSpeed * (16.0934/36)
    return(c2)
