Reorder the q matrices based on the grouping variable

This function reorders the q matrices in a gt_admix object based on the grouping variable. This is useful before plotting when the samples from each group are not adjacent to each other in the q matrix.

Usage

gt_admix_reorder_q(x, group = NULL)

Arguments

x

a gt_admix object, possibly with a grouping variable

group

a character vector with the grouping variable (if there is no grouping variable info in x)

Value

a gt_admix object with the q matrices reordered

Examples

example_gt <- example_gt("gen_tbl")

# Create a gt_admix object
admix_obj <- example_gt %>% gt_snmf(k = 1:3, project = "force")

# The $id in admix_obj is the same as in the gen_tibble
admix_obj$id
#> [1] "a" "b" "c" "d" "e" "f" "g"

# Reorder the q matrices based on the grouping variable
admix_obj <- gt_admix_reorder_q(admix_obj,
  group = example_gt$population
)

# The $id in admix_obj is now reordered according to the population
admix_obj$id
#> [1] "a" "b" "e" "c" "d" "f" "g"
