In sarp.snowprofile.alignment: Snow Profile Alignment, Aggregation, and Clustering

sarp.snowprofile.alignment 1.2.1

• Added the vignette Averaging of profiles and retrieval of distributions --> browseVignettes(package = "sarp.snowprofile.alignment")

sarp.snowprofile.alignment 1.2.0

• Added density and optical grain size (ogs) as warping variables for alignment
• Averaging of profiles:
  • include slab_rhogs, p_unstable, bdate, scalingFactor, ppu_all in warpSP and all dba routines
  • fix minor bugs for averaging shallow profiles and backtracking layers
  • add more detailed documentation (also for future developers)
• Robustify medoidSP

sarp.snowprofile.alignment 1.1.4

• Implemented functionality to align profiles without the requirement to re-scale them first! see examples in ?dtwSP
• simSP
  • includes several different approaches of computing snow profile similarities
  • can handle variable similarity values for non-matched layers
  • can apply penalty based on thickness of non-matched layers

• Implementation of Dynamic Time Warping Barycenter Averaging (dbaSP) enables to

  • average snow profiles. see also averageSP and averageSPalongSeason
  • connect layers within a profile set (backtrackLayers) to conveniently compute summary statistics and distributions of layers

• Minor scale changes:

  • Implemented ability to configure the absolute warping window (instead of relative one only)
  • Included first systematic tests (of various different alignment scenarios)
  • Fix bug in warpSP, which was introduced due to changes in the sarp.snowprofile::snowprofile data class (i.e., introduction of unobservedBasalLayers)
  • package shiny is not imported anymore, but only suggested --> enhances usability on clusters

sarp.snowprofile.alignment 1.0.0

• Updated license (GPL >= 3)
• Two new vignettes
• Adjust to upstream changes in sarp.snowprofile: new class (incl. methods) snowprofileSet (i.e., not backwards-compatible)
• Bug fixes:
  • rename remaining deprecated field names (e.g., grain_type to gtype, deposition_date to ddate, etc.)
  • make documentation available
  • interactive alignment shiny app is fixed
  • 'globalAlignment' has been made directional (i.e., bottom-up, top-down)

sarp.snowprofile.alignment 0.1.0

• first version tag
• main version 0.x to accompany paper submission
