Evaluate a delayed expression

Evaluate a delayed expression

delayed_eval(delayed_expr)

Arguments

delayed_expr	delayed expression generated with method `delayed_expr()``

Value

the evaluated expression

Examples

# define a delayed expression
x <- delayed_expr(size * 5 + 1)

# create a new expression
y = 1 + x + 5 * x - x

# generates an error, as size is not defined
delayed_eval(y)
#> Error in eval(delayed_expr$expr, parent.frame()): object 'size' not found

# calculates expression y using size
size = 0.1
delayed_eval(y)
#> [1] 8.5
