From bb0c7592055d684312c898db6252f4efc06d9485 Mon Sep 17 00:00:00 2001 From: Mason Garrison Date: Wed, 11 Feb 2026 13:20:04 -0500 Subject: [PATCH 01/46] Add twinID support and mz_twins option MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduce twinID parameter across pedigree segmentation functions (ped2fam/.ped2id/ped2graph/ped2maternal/ped2paternal) and thread it through calls so twin IDs are considered when building family/graph structures. Add mz_twins logical option to ped2com (default FALSE) and, when TRUE and twinID is present, call addMZtwins(ped) to treat MZ twins as an additional parent–child relationship for relatedness computations. Also fix a minor typo in a comment. --- R/buildComponent.R | 10 +++++++++- R/segmentPedigree.R | 27 ++++++++++++++++++++------- 2 files changed, 29 insertions(+), 8 deletions(-) diff --git a/R/buildComponent.R b/R/buildComponent.R index 38a96522..cff3268e 100644 --- a/R/buildComponent.R +++ b/R/buildComponent.R @@ -19,6 +19,7 @@ #' @param isChild_method character.

This produces isPar[twin2, twin1] = 1.0 in the sparse matrix (two 0.5 entries summed), so path tracing yields relatedness 1 between MZ pairs. Users provide a twinID column (and optionally zygosity) and pass mz_twins=TRUE to ped2add()/ped2com(). DZ twins are left unchanged when zygosity column is present. https://claude.ai/code/session_01P3RQTYpWtAtheSqi4aPjR5 * Replace pedigree redirection with r2 column merge for MZ twins The previous approach redirected twin2's parents to twin1 in the pedigree, which inflated twin2's diagonal (1.5 instead of 1.0) and twin2-to-child relatedness (0.75 instead of 0.5). New approach: after path tracing but before tcrossprod, merge twin2's column into twin1's in the r2 matrix. MZ twins share the same genetic source, so this correctly produces: - MZ twin relatedness = 1.0 - Self-relatedness = 1.0 (no inflation) - Parent-child and all downstream values correct - No post-hoc diagonal patching needed https://claude.ai/code/session_01P3RQTYpWtAtheSqi4aPjR5 * Use symmetric column merge for MZ twins instead of zeroing Both twin columns now get the same normalized values (r2_merged = (col1 + col2) / sqrt(2)) so both twins remain present and contribute equally. Produces the same final relatedness matrix as the zero approach but without erasing one twin from the genetic source matrix. https://claude.ai/code/session_01P3RQTYpWtAtheSqi4aPjR5 * Merge-then-restore approach for MZ twins Temporarily absorb twin2's column into twin1's before tcrossprod, then copy twin1's row/col back to twin2 afterward. This keeps the computation correct while ensuring neither twin is erased from the final relatedness matrix. https://claude.ai/code/session_01P3RQTYpWtAtheSqi4aPjR5 * Accept lowercase 'mz' and add MZ twin tests Treat both "mz" and "MZ" as monozygotic in findMZtwins (zygosity check now uses %in% c("mz","MZ")). Minor formatting tweak to the verbose message. Added unit tests (tests/testthat/test-buildComponent.R) verifying that MZ twins are coded with relatedness 1 when mz_twins=TRUE, that siblings remain 0.5 when mz_twins=FALSE, self-relatedness stays 1, and parent-child relatedness is unchanged. * fix tests --------- Co-authored-by: Claude --- R/buildComponent.R | 38 ++++++++- R/constructAdjacency.R | 67 +++++++++++++++ man/adjustKidsPerCouple.Rd | 13 ++- man/buildBetweenGenerations.Rd | 13 ++- man/buildWithinGenerations.Rd | 13 ++- man/findMZtwins.Rd | 26 ++++++ man/ped2add.Rd | 3 + man/ped2com.Rd | 3 + man/ped2fam.Rd | 3 + man/ped2graph.Rd | 3 + man/ped2maternal.Rd | 3 + man/ped2paternal.Rd | 3 + man/simulatePedigree.Rd | 13 ++- tests/testthat/test-buildComponent.R | 114 +++++++++++++++++++++++++ tests/testthat/test-simulatePedigree.R | 10 +-- 15 files changed, 313 insertions(+), 12 deletions(-) create mode 100644 man/findMZtwins.Rd diff --git a/R/buildComponent.R b/R/buildComponent.R index cff3268e..71f28929 100644 --- a/R/buildComponent.R +++ b/R/buildComponent.R @@ -19,7 +19,7 @@ #' @param isChild_method character.

In data-raw/optimizing.R create r_mz1 and r_mz2 using ped2add with mz_method 'merging' and 'addtwins' and assert their sparse matrix internals (@i and @x) match. Update tests/testthat/test-buildComponent.R to loop over mz_method options when verifying parent/child relatedness for MZ twins and add an explicit equality assertion between the two method results. These changes ensure different mz_method implementations produce equivalent relatedness outputs. --- NEWS.md | 4 + R/buildComponent.R | 13 +- R/constructAdjacency.R | 10 +- R/segmentPedigree.R | 12 +- R/tweakPedigree.R | 27 +- data-raw/optimizing.R | 160 ++++++++++-- man/makeTwins.Rd | 5 +- man/ped2add.Rd | 1 + man/ped2com.Rd | 1 + tests/testthat/test-buildComponent.R | 24 +- .../figure-html/unnamed-chunk-7-1.png | Bin 0 -> 6479 bytes vignettes/v5_ASOIAF.html | 247 ++++++++++-------- 12 files changed, 351 insertions(+), 153 deletions(-) create mode 100644 vignettes/v2_pedigree_files/figure-html/unnamed-chunk-7-1.png diff --git a/NEWS.md b/NEWS.md index 92292f4a..dcab85d1 100644 --- a/NEWS.md +++ b/NEWS.md @@ -1,6 +1,10 @@ # BGmisc NEWS # Development version: 1.6.0.9000 +Add option for MZ twins in the additive genetic matrix + +Add option to select sex for MZ twin generation. + # BGmisc 1.6.0.1 * Add helper functions for checkParents etc * fixed incorrect direction so that parents are pointing to children in the graphs diff --git a/R/buildComponent.R b/R/buildComponent.R index 8cae7df8..926398cd 100644 --- a/R/buildComponent.R +++ b/R/buildComponent.R @@ -124,14 +124,12 @@ ped2com <- function(ped, component, ped <- standardizeColnames(ped, verbose = config$verbose) } - + mz_pairs <- NULL if (mz_twins == TRUE && "twinID" %in% colnames(ped)) { - mz_pairs <- NULL mz_pairs <- findMZtwins(ped, verbose = config$verbose) } - # Load final result if computation was completed if (config$resume == TRUE && file.exists(checkpoint_files$final_matrix)) { if (config$verbose == TRUE) cat("Loading final computed matrix...\n") @@ -145,11 +143,9 @@ ped2com <- function(ped, component, c(ped$ID[pair[1]], ped$ID[pair[2]]) }) - for (id_pair in mz_pairs) { - - + for (id_pair in mz_pairs) { twin1_id <- id_pair[1] - twin2_id <- id_pair[2] + twin2_id <- id_pair[2] twin2_row <- which(ped$ID == twin2_id) # Make twin2 a founder @@ -159,7 +155,6 @@ ped2com <- function(ped, component, # Redirect twin2's children to twin1 ped$momID[ped$momID == twin2_id] <- twin1_id ped$dadID[ped$dadID == twin2_id] <- twin1_id - } } if (config$verbose == TRUE) { @@ -167,8 +162,6 @@ ped2com <- function(ped, component, } - - #------ # Algorithm #------ diff --git a/R/constructAdjacency.R b/R/constructAdjacency.R index d779937b..fc76e8dd 100644 --- a/R/constructAdjacency.R +++ b/R/constructAdjacency.R @@ -618,11 +618,15 @@ findMZtwins <- function(ped, verbose = FALSE) { pairs[[length(pairs) + 1]] <- c(idx1, idx2) if (verbose) { - message("MZ twin pair found: ", twin_id, " (row ", idx1, - ") and ", co_twin_id, " (row ", idx2, ")") + message( + "MZ twin pair found: ", twin_id, " (row ", idx1, + ") and ", co_twin_id, " (row ", idx2, ")" + ) } } - if (length(pairs) == 0) return(NULL) + if (length(pairs) == 0) { + return(NULL) + } return(pairs) } diff --git a/R/segmentPedigree.R b/R/segmentPedigree.R index 0b4921e8..d74abfb3 100644 --- a/R/segmentPedigree.R +++ b/R/segmentPedigree.R @@ -33,8 +33,10 @@ ped2fam <- function(ped, personID = "ID", twinID = "twinID", ...) { # Call to wrapper function - .ped2id(ped = ped, personID = personID, momID = momID, dadID = dadID, famID = famID, twinID = twinID, - type = "parents") + .ped2id( + ped = ped, personID = personID, momID = momID, dadID = dadID, famID = famID, twinID = twinID, + type = "parents" + ) } .ped2id <- function(ped, @@ -43,8 +45,10 @@ ped2fam <- function(ped, personID = "ID", type, ...) { # Turn pedigree into family - pg <- ped2graph(ped = ped, personID = personID, momID = momID, dadID = dadID, twinID = twinID, - adjacent = type) + pg <- ped2graph( + ped = ped, personID = personID, momID = momID, dadID = dadID, twinID = twinID, + adjacent = type + ) # Find weakly connected components of graph wcc <- igraph::components(pg) diff --git a/R/tweakPedigree.R b/R/tweakPedigree.R index 88f96128..ca7dba99 100644 --- a/R/tweakPedigree.R +++ b/R/tweakPedigree.R @@ -9,6 +9,7 @@ #' @param verbose logical.
