In RZooRoH: Partitioning of Individual Autozygosity into Multiple Homozygous-by-Descent Classes

RZooRoH 0.4.2

• Improved memory usage - in particular for parallel computing
• More efficient computation of allele frequencies (C functions)
• Improved management of convergence problems:
• possibility to automatically restart analysis in case of convergence problems by providing multiple optim methods or starting values for mixing coefficients,
• improved error message, information on problematic individuals (or pairs),
• added @optimerr slot to kinship results
• Improved numerical properties for 'Interval' models (better stability with very low values)
• New modelling of the minimum rate in MixKL models (compatible with more optim methods)
• New options to provide map directly in cM or in physical position but with a cM-to-Mb ratio different from 1
• Added new accessor functions for kinship results (update and merge), extended update and merge functions to IBD analyses
• Added new accessor function to estimate inbreeding coefficients based on identified HBD segments
• Corrections of minor bugs
• Updated documentation according to changes and clarified links between mixing coefficients and inbreeding rates per layer, and between "rates" and rates of coancestry changes
• Updated documentation on conversions (using PLINK2 and dosage formats)
• Modifications to the vignette, including advice for memory management and handling convergence problems
• Set freqem to TRUE by default
• Updated citations
