In rabutler-usbr/knnstdisagg: Nonparametric Space-Time Streamflow Disaggregation Using KNN

knnstdisagg 0.2.1

Released September 7, 2023

Minor non API breaking changes

• knnst_spatial_cor(), knnst_temporal_cor() (#34), and plot.knnst() now work when there is more than one simulation. (#34)
• Small syntax/function updates for newer versions of ggplot2 and tidyr

Bug fixes

• Fixed labeling of PDFs (they were previously labeled CDFs) (#35)
• Fixed formatting of README generated by write_knnst() (#36)

knnstdisagg 0.2.0

Released April 16, 2020

API Breaking Changes

• plot.knnst() was changed in multiple ways, several which break any previous calls to it.
  • The default value for site was removed as it does not make sense to guess site names when they will typically be unique.
  • Stats for the disaggregated data are now computed on a user specified bin_size. bin_size is a new argument to plot.knnst() with no default. (#32)
  • The use of ... was modified so that it is now only used for color, size, and shape. Default color, size, and shape were added for instances when these are not user specified.

Additions and Enhancements

• Added spatial and temporal correlation functions and plots. (#29, #30)
• knnst_spatial_cor() computes spatial correlation between sites.
• knnst_temporal_cor() computes temporal (monthly) correlation at one site.
• plot.knnst_spcor() and plot.knnst_tmpcor() plot the results of knn_spatial_cor() or knn_temporal_cor()
• Added random_seed argument to knn_space_time_disagg() and knn_get_index_year() to assist with reproducibility. (#28)
• Changed how unnamed mon_flow input to knn_space_time_disagg() is treated. Now the columns (sites) are renamed in knn_space_time_disagg(), instead of in as.data.frame.knnst(). This ensures the site names always exist for any subsequent code, rather than having to convert to a data.frame to get the site names. (#33)
• write_knnst() now saves a README.txt file (#25) and includes the yyyy-mm row names in the saved csv files that include the monthly disaggregated data.
• ex_disagg is now an exported data object. It contains an example knnst object for use in examples and tests.

Bug Fixes

• Fixed bug related to how lag-1 correlation was computed for the historical/pattern data. This only affected January values if the start of the year was a month other than January. (#27)
