cumsums_extractList_sapply is a reduced version of the bioC2_cc_iqw currently
used in consensusClustersGR.
cumsums_extractList_sapply <- function(ctss, clusters) {
# Fill gaps with zeros
fill <- GPos(clusters)
score(fill) <- Rle(0L)
ctss <- c(ctss, fill[!fill %in% ctss]) |> sort()
o <- findOverlaps(query = clusters, subject = ctss)
grouped_scores <- extractList(score(ctss), o)
sapply(grouped_scores, cumsum)
}
cumsums_extractList_sapply_res <- cumsums_extractList_sapply(ctss, clusters)
cumsums_extractList_aslist <- function(ctss, clusters) {
# Fill gaps with zeros
fill <- GPos(clusters)
score(fill) <- Rle(0L)
ctss <- c(ctss, fill[!fill %in% ctss]) |> sort()
o <- findOverlaps(query = clusters, subject = ctss)
grouped_scores <- extractList(score(ctss), o)
cumsum(grouped_scores) |> as.list()
}
cumsums_extractList_aslist_res <- cumsums_extractList_aslist(ctss, clusters)
cumsums_extractList_RleList <- function(ctss, clusters) {
# Fill gaps with zeros
fill <- GPos(clusters)
score(fill) <- Rle(0L)
ctss <- c(ctss, fill[!fill %in% ctss]) |> sort()
o <- findOverlaps(query = clusters, subject = ctss)
grouped_scores <- extractList(score(ctss), o)
cumsum(grouped_scores)
}
cumsums_extractList_RleList_res <- cumsums_extractList_RleList(ctss, clusters)
The results are almost the same. The differences appear to be rounding errors.
