Usage

conditions(
  x,
  drop.empty = TRUE,
  expand_basis = FALSE,
  style = c("canonical", "display"),
  ...
)

# S3 method for class 'event_model'
conditions(x, drop.empty = TRUE, expand_basis = FALSE, style = c("canonical", "display"), ...)

# S3 method for class 'event_term'
conditions(x, drop.empty = TRUE, expand_basis = FALSE, style = c("canonical", "display"), ...)

Arguments

x: The object to extract conditions from.
drop.empty: Logical whether to drop conditions with no events (default: TRUE).
expand_basis: Logical whether to expand basis functions (default: FALSE).
style: Naming style. "canonical" returns fully qualified internal names, while "display" returns shorter user-facing labels.

Value

A character vector of condition names.

Examples

term <- event_term(
  list(condition = factor(c("A", "B", "A"))),
  onsets = c(0, 10, 20),
  blockids = c(1, 1, 1)
)
conditions(term)
#> [1] "condition.A" "condition.B"
conditions(term, style = "display")
#> [1] "A" "B"
conditions(term, expand_basis = TRUE)
#> [1] "condition.A" "condition.B"
