  • changed default order of alleles from their frequency to internal coding
• all plot functions:
  • allow user to set plot margins
  • allow user to overwrite some plot parameters such as “xlab” and “ylab”

• Enabled data input from vcf files and the simulation program ‘ms’
• Calculation and visualization functions have been separated
• Added support for handling unphased haplotypes and unpolarized markers
• Output in form of matrices has been replaced by data frames
• Simplified column names in data output (use only capital letters and underscores)
• Improved visualization of furcation trees
• Added visualization of shared haplotype lengths
• Added simple function to delineate candidate regions of selection
• Added options to yield virtually identical results with program hapbin
• Made all plots more customizable
• Added new vignette with in-depth discussion of example files
• Disagreement between code and vignette about uni-lateral p-value for Rsb/XP-EHH has been cleared

rehh 2.0.4 (February 13, 2019)

• Corrected implementation of maxgap in combination with discard_integration_at_border=FALSE
• Added parameter scalegap
• Included section about gaps in vignette, added details in comparison with hapbin, corrected rendering
• Corrected paper title in CITATIONS

rehh 2.0.3 (June 12, 2017)

• Inactivation of graphical display in multiple windows (i.e., plot.new calls) in the calc_ehh, calc_ehhs, ihsplot, rsbplot, xpehhplot and distribplot functions
• Minor corrections in the manual pages

rehh 2.0.2 (November 15, 2016)

• Option maxgap modified (functions return NA value if not satisfied)
• Example data sets removed from the rehh package and included in the newly developed rehh.data package. The function make.example.files() was modified accordingly.

rehh 2.0.1 (October 24, 2016)

• Option maxgap added to the calc_ehh, calc_ehhs and scan_hh functions

rehh 2.0.0 (July 30, 2016)

• Major modification of the algorithm to explore haplotype variability (more than one order of magnitude faster), including parallelization
