Construct a design for a vectorized RSA model — vector_rsa

This function constructs a design for an RSA model using a single distance matrix, labels, and blocks.

Usage

vector_rsa_design(D, labels, block_var)

Arguments

D: A representational dissimilarity matrix with row.names indicating labels.
labels: character vector of labels corresponding to rows in another dataset X.
block_var: A vector indicating the block (strata) each label belongs to. Must be the same length as `labels`.

Value

A list containing the elements of the RSA design, class attributes "vector_rsa_design" and "list".

Details

The function verifies that all `labels` appear in `rownames(D)` and creates an expanded dissimilarity matrix (`Dexpanded`) matching the order of `labels`.

Examples

# \donttest{
  D <- as.matrix(dist(matrix(rnorm(5*3), 5, 3)))
  rownames(D) <- colnames(D) <- letters[1:5]
  labels <- factor(rep(letters[1:5], 2))
  block_var <- rep(1:2, each=5)
  des <- vector_rsa_design(D, labels, block_var)
# }
