assert_has_terms

From assertive.models v0.0-2 by Richard Cotton

Does the input have terms?

Checks to see if the input has a terms component or attribute.

Usage

assert_has_terms(x, severity = getOption("assertive.severity", "stop"))
has_terms(x, .xname = get_name_in_parent(x))

Arguments

x: Input to check.
severity: How severe should the consequences of the assertion be? Either "stop", "warning", "message", or "none".
.xname: Not intended to be used directly.

Value

has_terms returns TRUE if the input has an element or an attribute named terms. assert_has_terms returns nothing but throws an error if has_terms is not TRUE.

Examples

# NOT RUN {
model <- lm(uptake ~ conc, datasets::CO2)
# this works because model$terms is not null
assert_has_terms(model)
# }
