The mutate family of functions within dplyr is convenient when converting columns, offering a streamlined approach. Here are some other conversion tutorials:

Real-world data scenarios, e.g., Psychology, may require careful column conversion. Consider instances where survey responses, initially stored as characters or sometimes null values, need transformation into a numeric format for meaningful analysis. Such data manipulation tasks are critical for accurate statistical insights and form the backbone of data preprocessing in psychological research.

Whether dealing with questionnaire data, experimental results, or any diverse datasets common in Psychology, mastering the art of converting multiple columns to numeric in R empowers analysts to derive richer insights from their data.
