Get stored analysis object

Retrieve a full analysis object (prcomp, hclust, etc.) that was stored using a compute_* function.

Usage

get_analysis(x, name)

Arguments

x

A tidymatrix object

name

Name of the analysis to retrieve

Value

The stored analysis object (class depends on analysis type)

Examples

tm <- tidymatrix(matrix(rnorm(100), 10, 10))
tm <- tm |>
  activate(columns) |>
  compute_prcomp(name = "pca")

# Get the full prcomp object
pca_obj <- get_analysis(tm, "pca")
summary(pca_obj)
