# rsinaica 1.2.0

* `sinaica_station_data` now supports downloading two years of data

  ```R
  df <- sinaica_station_data(271, "O3", "2015-09-11", "2017-09-11", "Crude")
  ```
* Remove duplicate stations from the `stations_sinaica` data.frame
* Added function `sinaica_station_dates()`, which lists the dates for which a 
  station has data available.
  
  ```R
  sinaica_station_dates(271, "Crude")
  ```  
* Added function `sinaica_station_params()`, which lists the air quality 
  parameters measured at a station for which SINAICA provides data.
  
  ```R
  sinaica_station_params(271, "Crude")
  ```  
* Added two new air quaility stations in Ensenada and Tecate to 
  `stations_sinaica`
