ecr 2.2.1

Fixes

Fixed warnings raised by r-devel versions
Fixed typo in the docs of approximateRefSets yielding the function not being exported

Fixed bug in mutPolynomial where parameter lower was sanity-checked twice and upper not at all
Fixed some typos in function documentations
Fixed bug in updateParetoArchive: optimization direction, e.g., minimize first, maximize second objective are now respected

Performance assessment for stochastic multi-objective optimization algorithms (very powerful tool)
- Flexible scatterplots in 2D and 3D
- Function to calculate a set of unary and binary performance indicators for a set of problems and algorithms
- Function to visualize indicator distrbutions
- Functions to perform statistical tests and output results as well-formatted LaTeX tables
Exported helper functions getNumberOfChildren, getNumberOfParentsNeededForMating and generatesMultipleChildren

Fixed: bug in replaceMuCommaLambda if n.elite was not set by hand
Fixed: selGreedy throws error if n.select is larger than the number of individuals passed (this led to hard-to-detect errors in (mu, lambda) strategies and white-box approach)

uniform crossover recombinator recUnifCrossover
parameter log.stats for ecr function (possibility to define fitness statistics to be logged)
logical log.pop argument for ecr function (should each population be saved in the logger?)
possibility to store additional stuff in logger via ‘extras’
terminators stopOnEvals and stopOnOptY
