climatrends 0.2 (2022-02-14) Unreleased

  • Fix an issue in computing large areas with nasapower
  • Add paper

climatrends 0.1.7 (2020-05-22) 2020-05-22

  • Add suggested CITATION
  • Fix documentation typos
  • Fix a bug in computing equation ‘c’ in GDD()
  • Improve speed of functions GDD() and late_frost()
  • package ‘sf’ is a suggestion not dependency

climatrends 0.1.6 (2020-05-19) 2020-05-20


  • New function crop_sensitive() to compute crop sensitive indices.
  • New function late_frost() to compute late spring frost.
  • Export function get_timeseries()
  • Enable future modular expansion of data sources using API clients by creating specific functions that are called with the argument data.from in get_timeseries()
  • Enable argument, optional to span, when indices are retrieved with focus on time series analysis
  • Enable data retrieve from large areas in ‘nasapower’ by clustering the lonlat points with stats::hclust()
  • Methods for objects of classes ‘vector’ (default), ‘matrix’, ‘array’, ‘data.frame’ and ‘sf’. The last two with focus in retrieve data from external sources.
  • Remove dependency from ‘tibble’ which was basically to provide a ‘cool’ printing method
  • Implement a print() method for objects that inherits the class ‘clima_df’
  • Calls from “nasapower” can be adjusted with argument pars, mainly for temperature(), GDD() and ETo(). Details in the function documentation
  • New temperature() indices provided. Details in the function documentation
  • Function GDD() applies two equations adjustments for cold zones and one for warm zones with the argument equation. Details in the function documentation
  • Function GDD() now allows to return the raw daily gdd or number of days to reach the accumulated gdd (the default in previous versions) using the argument


  • New default method in all functions which uses a vector as main input
  • Change order of GDD() arguments. Previous versions used GDD(object, = NULL, degree.days = NULL, base = 10, span = 150, ...). From now on GDD() default behaviour is GDD(object, ..., base = 10), with additional arguments are passed through ... in each defined method. The function return by default the accumulated degree-days across the series.

climatrends 0.1.0 (2020-02-20) 2020-02-28
