Insert a step into a design (deprecated)

Deprecated in 2.0, and warns once per session. Reconstruct the design with + instead.

Usage

insert_step(design, new_step, before = NULL, after = NULL)

Arguments

design

(required) A design.

new_step

(required) A design_step to insert.

before, after

(required) A label, integer, or design_step indicating the anchor point. Provide exactly one of the two; if both are given, after is used. before comes first, as in DeclareDesign 1.x, so a script that passed the anchor by position keeps its meaning.

Value

A design with new_step inserted at the anchor.

Examples

design <- declare_model(N = 30, Y = rnorm(N)) +
  declare_inquiry(mu = mean(Y))
new_design <- insert_step(design,
  declare_measurement(Y2 = Y * 2),
  after = "model")
