gatbxr 0.2.0

Package metadata

• Credited the authors and copyright holders of the original Sheffield ‘MATLAB’ toolbox in Authors@R.
• Changed the license to GPL (>= 2), as required for a derived work of the GPL-licensed original toolbox.
• Revised Title and Description following CRAN review.

Bug fixes

• xovmp() and all xov*() crossover functions: the crossover probability Px was inverted (pairs were crossed when they should not be), and the single-point cut was always placed after the first locus.
• recmut(): the second offspring of each pair now moves in the opposite direction (-Diff) as in the original toolbox, and identical parent norms no longer cause division by zero.
• bs2rv(): fixed decoding when lbin = FALSE; lb, ub, code, scale, lbin and ubin may now be given per variable.
• crtbp(): fixed argument handling when Lind contains a base vector, and added informative errors for unsupported argument combinations.
• ranking(): individuals with equal objective values now receive the same (average) fitness; RFun = NULL now works as documented.
• migrate(), mutate() and select() failed with their default arguments on R >= 4.2.0.
• reins(): InsOpt of length 1 now works as documented.
• scaling(): no longer returns NaN when all objective values are equal.

Documentation

• Added examples to all exported functions and fixed spelling throughout.
• Corrected author attributions in several help pages.
