Evaluate code in qenv

Evaluate code in qenv

Usage

eval_code(object, code, ...)

Arguments

object

(qenv)

code

(character, language or expression) code to evaluate. It is possible to preserve original formatting of the code by providing a character or an expression being a result of parse(keep.source = TRUE).

...

(dots) additional arguments passed to future methods.

Value

qenv environment with code/expr evaluated or qenv.error if evaluation fails.

Details

eval_code() evaluates given code in the qenv environment and appends it to the code slot. Thus, if the qenv had been instantiated empty, contents of the environment are always a result of the stored code.
