aqp 1.27

Enhancements / Bug Fixes

• mixMunsell now relies on suggested package {gower} for 5-10x speed bump
• {aqp} no longer imports from {reshape} (less one dependency), all transformations from wide<->long are done via {data.table}
• methods from {data.table} are now imported by {aqp} (new dependency)
• Major overhaul of plotColorQuantiles(), now using {lattice} graphics
• Argillic critical clay contents crit.clay.argillic rounded to whole numbers per NSSH Part 614, subpart B, sections 614.13 and 614.14
• mutate_profile uses data.table::rbindlist(fill=TRUE) to combine site- and horizon-level transformations
• updates to horizon boundary encoding functions (hzTopographyCodeToOffset, hzTopographyCodeToLineType, hzDistinctnessCodeToOffset)
• plotSPC updates:
  • argument named changes: hz.boundary.lty is a horizon-level attribute that contains line type codes
  • hz.topography.offset a horizon-level attribute that contains representative offsets that encode horizon boundary topography
  • plotSPC now encodes hz.topography.offset using a vertical "bump" (chevron)
• addBracket can now accept multiple bracket annotations per profile

New Functions / Data

• New dataset equivalent_munsell and method equivalentMunsellChips for "equivalent" Munsell chips lookup list based on all pairwise dE00 contrasts for integer "chips" in {aqp} munsell data set
• new function L1_profiles computes multivariate (L1) medians, compare to marginal medians via slab
