Extract Executable R Code from LLM Response Text

Parses code fence blocks (```r ... ```, ```R ... ```, ``` ... ```) out of LLM responses. If multiple fences exist, concatenates them. If no fence is found, falls back to the trimmed raw text. Strips extraneous whitespace and returns valid R code.

Usage

sv_extract_code(response_text)

Arguments

response_text

Character vector containing the LLM response text.

Value

A character string of extracted R code.
