Core Functions of R Code Wizard

  • Data Filtering

    Example Example

    Using dplyr's filter() to extract rows based on specific conditions. Example: filter(df, age > 50)

    Example Scenario

    A healthcare data analyst might use this to select patient records where the age is greater than 50 to focus on a senior patient cohort for a study on arthritis prevalence.

  • Column Selection

    Example Example

    Using dplyr's select() to focus on certain columns of interest. Example: select(df, starts_with('income'))

    Example Scenario

    A financial analyst can use this function to retrieve all columns related to income from a dataset during an audit of income distribution among different demographics.

  • Data Summarization

    Example Example

    Using dplyr's summarise() along with group_by() to compute summaries like means or counts. Example: df %>% group_by(gender) %>% summarise(average_age = mean(age, na.rm = TRUE))

    Example Scenario

    In market research, summarizing data by customer demographics can help identify which gender groups are purchasing certain products more frequently, assisting in targeted marketing strategies.

  • Data Mutation

    Example Example

    Using dplyr's mutate() to create new columns based on existing data. Example: mutate(df, new_salary = salary * 1.1)

    Example Scenario

    A HR manager might use this to calculate adjusted salaries after a planned salary increase of 10% for budget projection reports.

  • Data Joining

    Example Example

    Using dplyr's inner_join(), left_join(), etc., to merge datasets based on a common key. Example: left_join(employees, departments, by = 'dept_id')

    Example Scenario

    An operations analyst may merge employee and department data to evaluate staffing levels and departmental costs, facilitating resource planning.
