Representational connectivity design helper (ReNA-RC)

Source: R/rena_design.R
repnet_design.Rd

Build a design object for representational connectivity, specifying item keys, a seed RDM, and optional confound RDMs.

Usage

repnet_design(design, key_var, seed_rdm, confound_rdms = NULL)

Arguments

design

An mvpa_design object (as used elsewhere in rMVPA).

key_var

Column name or formula giving item identity (e.g. ~ ImageID).

seed_rdm

A K x K matrix or "dist" object; rows/cols labelled by item IDs.

confound_rdms

Optional named list of K x K matrices or "dist" objects, used as nuisance RDMs (e.g. block, lag, behavior).

Value

A list with fields:

  • key: factor of item IDs (length = nrow(design$train_design))

  • seed_rdm: seed RDM as a matrix with row/colnames

  • confound_rdms: named list of confound RDM matrices

Examples

if (FALSE) { # \dontrun{
  des <- repnet_design(design, ~ ImageID, seed_rdm=my_rdm)
} # }
