Usage

get_q_matrix(x, ..., k, run)

Arguments

x

A gt_admix object containing multiple Q matrices

...

Not used

k

The k value of the desired Q matrix

run

The run number of the desired Q matrix

Value

A single Q matrix from the gt_admix object

Examples

example_gt <- example_gt("gen_tbl")

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

# Extract a Q matrix
get_q_matrix(admix_obj, k = 3, run = 1)
