cercospoRa 0.0.2 (2025-05-23)

Bug fixes

• fix variable assignment bug, see issue #41

Minor improvements

• Improved estimations of cultivar susceptibility on epidemic onset date issue #38 and #42
  • relative humidity thresholds are now a variable on calc_epidemic_onset() #40
  • Argument in calc_epidemic_onset_from_image() cc_r changed from c_closure This is for clarity as the function calc_epidemic_onset has the same argument which expects a different input to calc_epidemic_onset_from_image()

Documentation improvements

• Clarify cultivar susceptibility references and bsa index.
  • Update README
  • Add spelling package to suggests
  • Corrected unit tests
  • Expand vignette to look at range of pixelwise epidemic onsets.
  • Formatting and grammar improvements

cercospoRa 0.0.1 (2024-12-13)

minor improvements

• moved format_weather function into cercospoRa package to avoid epiphytoolR suggests problems with CRAN.
  • Moved some ./ext data to internal data for testing only to reduce package size.
  • weathr data attribution updated

cercospoRa 0.0.0.9003

New Features and minor improvements

• Four functions have been added to deal with spatial heterogeneity:
  • read_sb_growth_parameter: read in and format raster images to allow further computation.
  • calc_r_x0: fit logistic growth curve to the date.
  • calc_c_closure: to deduct canopy closure dates from the fitted curves.
  • calc_epidemic_onset_from_image: builds on the existing calc_epidemic_onset function to compute a value for each pixel.
  • Example datasets have been provided to check the functions. It consists of a folder containing two LAI maps computed from UAV images.

Features removed

• Removed methods from Racca paper and set them to a new branch plus_racca

Documentation fixes

• add metadata
  • Further simplification of main and dev branches to only the Wolf and Verreet functions.
  • add badge
  • spelling and grammar fixes

cercospoRa 0.0.0.9001

• Change package name
• Add pkgdown site
• Reduce functions to only those described by Wolf and Verreet (2005)
