Changes in version 4.0.2 (2026-02-26) Changed - Updated import.vcf INFO-field tests to be robust to upstream vcfR::vcfR2tidy() schema additions (e.g., VariantKey) and avoid CRAN failures. Changes in version 4.0.1 (2026-01-23) Changed - Updated Paul Boutros email to @sbpdiscovery.org Changes in version 4.0.0 (2025-08-20) Changed - Refactored all main functions for gains in RAM efficiency and runtime - Introduced a breaking change to the output of import.vcf. The outputed list object has a different naming scheme and different data formats. Previous data formats are still supported by setting long.format to TRUE, however the naming scheme is still changed. - Introduced a breaking change to apply.polygenic.score. The expected default vcf.data input format has changed. The previous input format is still supported by setting vcf.long.format to TRUE from the default FALSE. Added - Added support for more efficient storage and manipulation of imported VCF data. The default output of import.vcf now returns VCF data in a split format. A data.table object contains VCF data from fixed fields (CHROM, POS, ID, REF, ALT). A matrix object contains sample-specific genotypes in allele-format in a sample (columns) by variant (rows) matrix. Changes in version 3.1.0 Changed - Fixed regression of combine.vcf.with.pgs() function that prevented it from handling multiple rsIDs on the same line. - Fixed bug caused by the case of a sample-specific missing variant at a multiallelic site - Use updated R CMD check CI/CD action with renv dependency management Added - Added new contributor - Added minimum sample size check for grouped density curves - Added new plotting function create.pgs.boxplot - Added option for user to provide custom PGS source column(s) for plotting functions - Added option to assess.pgs.vcf.allele.match to condition the handling of ambiguous strand flips on the total number of unambiguous strand flips. - Added new function analyze.pgs.binary.predictiveness which given a PGS and phenotypes runs a logistic regression and returns statistics (OR, p-value, AUC) describing how well the PGS predicts the phenotype. It also automatically plots a receiver-operator-curve. Changes in version 3.0.2 Changed - ApplyPolygenicScore released on CRAN! Updated README with CRAN links. Changes in version 3.0.1 (2025-03-05) Added - Added hemizygous allele handling to dosage calculation - Added toggle to hexbinplot at sample size threshold in create.pgs.with.continuous.phenotype.plot Changed - Updated INDEL effect switch reporting by strand flip checker - Updated data structuring for automated statistical analysis in apply.polygenic.score Changes in version 3.0.0 Added - Added handling of overlapping deletion allele notation - Added secondary PGS/VCF variant matching method using rsID after first attempt with genomic coordinates - Added checks for rsID as an optional column in input PGS weight files - Added functionality to assess allele matches and correct strand flips Changes in version 2.0.0 Changed - Renamed functions starting with reserved vocabulary for S3 generic methods merge. -> combine. Changes in version 1.0.0 - First release Changes in version 0.1.0 - INITIAL FEATURES
