fasstr 0.3.0
=========================

Updated: 14 May 2019

#### Updates:

  * Removed logical "water_year" argument and now "water_year_start" controls the start of year alone (default now 1 for January)

  * Renamed 'include_year' argument to 'add_year' for some functions
  * complete_full_analysis just creates R objects; a new write_full_analysis saves the results in a single Excel document, with some plots in a plots folder; renamed 'sections' to 'analyses'
  * add_date_variables() outputs changed slightly to match new water_year_start argument
  * Replaced NULL and NA default values for function arguments to nothing, cleaning up documentation.
  * Replaced the package writexls with openxls for more functionality
  * Plotting: changed facet wrap labels, changed trending symbols
  * WSC station numbers with lower-case letters now accepted (08nm116 and 08NM116 both work)
  * basin_area argument as list now will default to HYDAT area if not listed, otherwise NA
  * Return Period axis has returned to the frequency analysis plot
  * Updated all documentation examples
  * Internal coding (MonthName levels coding cleaned up) 

#### New:

  * calc_longterm_monthly_stats and plot_longterm_monthly_stats that summarizes annual monthly mean flows data
  * calc_longterm_daily_stats and plot_longterm_daily_stats that summarizes daily mean flows data (calc_longterm_stats equivalent)
  * write_full_analysis writes the full analysis and doesn't create any objects in R
  * testthat functions for testing package (internal usage)

  
#### Bugs Fixed:

  * No warning now in annual functions if NA values produced for years listed in "exclude_years" argument
