substitute_q: A version of substitute that evaluates its first argument.

In biodatacore/biodatacoreUtils: Utilities for 'biodatacore' Packages

Description

This version of substitute is needed because substitute does not evaluate it's first argument, and it's often useful to be able to modify a quoted call.

Usage

substitute_q(x, env)

Arguments

x	a quoted call
env	an environment, or something that behaves like an environment (like a list or data frame), or a reference to an environment (like a positive integer or name, see as.environment for more details)

Examples

x <- quote(a + b)
substitute(x, list(a = 1, b = 2))
substitute_q(x, list(a = 1, b = 2))
