This release provides new functionality with regard to ionic ratios and plotting them in a Van Wirdum diagram (#114):

• New function calculate_ir() to compute the ionic ratio.
• New function ggplot_vanwirdum_background() to get a Van Wirdum diagram as ggplot object (without custom data), to which data layers can be added by the user.
• New vignette on plotting chemistry data: vignette("v230_chem_plots").

• get_locs() now substitutes filterlength values of 0 m by 0.3 m (#108). Before, this was only done for missing filterlengths.
• Harden get_chem() with regard to the iron / conductivity ratio calculation (used by the en_fecond_threshold argument) (#122):
  • Limit the calculation to the requested locations.
  • Set as missing if conductivity is set as zero in the data warehouse, and present a warning in case this occurs.
• Apply tidyverse code style (#119).
• Various maintenance.

• Move package {KSgeneral} to Suggests (#103). This avoids package breaking when {KSgeneral} is not available on CRAN. For the moment not taking further measures to protect against it, as the package is currently back on CRAN.

• Fixed non-working get_xg3() and get_chem() for data frame input, by avoiding the currently defunct dbplyr::db_drop_table() (#89, 08bc66d).
• Various maintenance (#81, #86, #87, #88, c382499).

• This release has been made compatible with dbplyr 2.0.0 (on CRAN); the dbplyr fork is not needed anymore (e66e58f, #74).
  • Follow the installation procedure on the homepage (readme) to upgrade.
  • Lazy results of get_locs(), get_xg3() and get_chem() are not sorted anymore. Sorting is done in tibbles only, i.e. if collect = TRUE. For more information, consult the Note added in the documentation of these functions.
• Fix broken selectlocs_xg3() and selectlocs_chem() (#73).
• Fix get_locs() error when no locations remain after spatial masking (c96421e).
• Fix get_locs() error when obswell_aggr = "mean" (#80).
• Adopt further inbodb functionality (#75):
  • re-export its dbDisconnect();
  • transfer handling of character encoding to inbodb.
• Improve documentation and pkgdown website (#76, #77, 3986b4e).

• New function cluster_locs() to spatially cluster locations (well clusters) (#39)
• More fun with get_locs():
  • optionally allow groundwater piezometers with missing filterdepth (argument filterdepth_na)
  • optionally replace missing filterdepth values in a conservative way, based on tubelength (argument filterdepth_guess, #44)
  • return eight more observation well attributes beside filterdepth (#44)
  • four methods are available to aggregate observation well attributes per location (argument obswell_aggr, #44)
  • applying a spatial mask is now a little speedier (#57)
• as_points() and get_locs() return a warning when duplicated coordinates occur in their local result (#51, thanks @w-jan)
• Package dependency moved from inborutils to inbodb: this is a change within connect_watina() which should not affect its behaviour and which reduces overall package dependencies.

Further, a number of smaller fixes and enhancements were made.

• Redo fix get_locs(): calculation of soilsurf_ost (#43)

• Bugfix in get_locs(): calculation of soilsurf_ost (#42)

• Bugfix in convertdf_enc() (#34)
• Some small documentation improvements

• Documentation is now generated by the newer roxygen2 version 7.0.2, resulting in a better layout of function arguments in the 'usage' section.

• On Windows, the functions now convert 'weird' characters from the data warehouse to proper UTF-8.
• Bugfix (#29) in get_locs() regarding the default implementation of the loc_validity argument.

• Fixed bug in some hyperlinks in function documentation, affecting the installation process on Windows (warnings were thrown).

• Several functions have been added to query and process chemical data.
• Three vignettes have been added.
• Improved various existing functionalities from version 0.1.0, based on user's feedback.
