Import admixture proportion files — import

Imports admixture proportions into long-format `ggpop_admix` S3 data for `plot_admix()` and `geom_admix()`. Directories are read as full multi-K ADMIXTURE result sets. `import_admix()` is the user-facing interface; `import_admixture()` is kept as a compatibility alias. When `pop_group` is supplied, population labels are joined by `sample_id` and drive pophelper-style group facets and sorting.

Usage

import_admix(file, type = c("auto", "structure", "admixture"), ind = NULL,
  pattern = "\\.Q$", recursive = FALSE, pop_group = NULL, ...)
import_admixture(file, type = c("auto", "structure", "admixture"), ind = NULL,
  pattern = "\\.Q$", recursive = FALSE, pop_group = NULL, ...)

Arguments

file: Path to one or more ADMIXTURE `.Q` files, a directory containing `.Q` files, or a limited STRUCTURE-like numeric matrix.
type: Input format: `admixture`, `structure`, or `auto`.
ind: Optional sample label file or data frame.
pattern: File pattern used when `file` is a directory.
recursive: Search directories recursively.
pop_group: Optional path or data frame with two columns, `sample` and `pop`, used for population group labels, sorting, and facets.
...: Additional arguments passed to `read.table()`.
