evaluate: Evaluate the value of a node

In jongbinjung/datree: Create and Manage Decision Trees for Decision Analysis

Description

evaluate uses lazyeval to evaluate the value function of any given node. Essentially a shortcut for calling lazyeval::f_eval on the $value object of a node.

Usage

evaluate(node, data = NULL, verbose = FALSE)

Arguments

node	Node list. The node to evaluate.
data	List-like. The data to be used when evaluating the value function. Depending on the value function, omitting the data may result in an error.
verbose	Logical. Whether or not to print the full value formula.

Value

Evaluated numeric value.

Examples

v <- o_node(v = ~ .data$x + y)
y <- 10
evaluate(v, data = list(x = 10))
evaluate(v, data = list(x = 1))
