formulas: Create a list of formulas

In modelr: Modelling Functions that Work with the Pipe

Create a list of formulas

Description

formulas() creates a list of two-sided formulas by merging a unique left-hand side to a list of right-hand sides.

Usage

formulas(.response, ...)

formulae(.response, ...)

Arguments

.response	A one-sided formula used as the left-hand side of all resulting formulas.
...	List of formulas whose right-hand sides will be merged to .response.

Examples

# Provide named arguments to create a named list of formulas:
models <- formulas(~lhs,
  additive = ~var1 + var2,
  interaction = ~var1 * var2
)
models$additive

# The formulas are created sequentially, so that you can refer to
# previously created formulas:
formulas(~lhs,
  linear = ~var1 + var2,
  hierarchical = add_predictors(linear, ~(1 | group))
)
