Value

Invisibly returns the path to the generated uncoded characters file

Examples

# Requires the CONFOR executable on the PATH.

try({
  delta <- load_delta(
    system.file("extdata", "chars_viola", package = "RDelta"),
    system.file("extdata", "items_viola", package = "RDelta"),
    system.file("extdata", "specs_viola", package = "RDelta")
  )
