Prompting Playbook for R

• Describe your data frame structure (column names, types, number of rows) before asking for transformation or visualization code, as R code is tightly coupled to data shape
• Specify whether you want tidyverse (dplyr/tidyr) or base R solutions, as AI tools default to tidyverse which may not match your project style or performance requirements
• When asking for statistical analysis, describe your study design (paired/unpaired, sample sizes, distribution assumptions) so the AI recommends appropriate methods
• For ggplot2, include your desired output format (publication-ready, interactive, dashboard) and any theme requirements to get properly styled visualizations
• When asking for R package development code, specify whether you use devtools/usethis conventions, roxygen2, and testthat, as package structure patterns vary significantly

Tidyverse data pipeline with ggplot2 visualization

A complete data analysis pipeline demonstrating dplyr transformations and ggplot2 visualization -- the R workflow where AI tools produce the most reliable output.

library(tidyverse)

analyze_sales <- function(sales_df) {
  monthly_summary <- sales_df |>
    mutate(month = floor_date(sale_date, "month")) |>
    group_by(month, region) |>
    summarize(
      revenue = sum(amount, na.rm = TRUE),
      orders  = n(),
      avg_order = mean(amount, na.rm = TRUE),

    ) |>
    mutate(growth = (revenue / lag(revenue) - 1) * 100, .by = region)

  plot <- monthly_summary |>
