plotcli 0.2.0

Major New Features

Enhanced ggplotcli: Universal ggplot2 Converter

The ggplotcli() function has been completely rewritten to render any ggplot2 plot in the terminal:

• 15 Supported Geoms: geom_point, geom_line, geom_path, geom_bar, geom_col, geom_histogram, geom_density, geom_smooth, geom_area, geom_segment, geom_hline, geom_vline, geom_rect, geom_text, geom_boxplot

• Legend Support: Automatic legends for color and fill aesthetics

• Faceting Support: Both facet_wrap() and facet_grid() work automatically

• Theme Auto-Detection: Automatically respects ggplot2 themes - theme_bw() adds borders and grids, theme_classic() shows only borders, etc.

• Multiple Canvas Types:

  • braille: Highest resolution using Unicode Braille patterns (2x4 dots per character)
  • block: Medium resolution using block elements
  • ascii: Basic ASCII characters for maximum compatibility

• Styling Options: Configurable borders, grid lines, titles, subtitles, captions, and axis labels

Boxplot Rendering

• New boxplot_style parameter: "ascii" (box-drawing characters) or "braille"
• Renders whiskers, box (Q1-Q3), median line, and outliers
• Perfect centering of whiskers and outliers

Optimized Color Mapping

• Intelligent color assignment minimizes repetition across groups
• 6 groups get 6 distinct terminal colors
• 8+ groups use all available colors before repeating
• Colors sorted by hue for visual consistency

Canvas Abstraction Layer

New R6-based canvas system providing:

• Pixel-level drawing primitives (points, lines, rectangles, circles, polygons)
• Automatic Braille character composition for smooth curves
• Support for colored output via ANSI escape codes

Geom Registry

Extensible system for adding custom geom handlers, making it easy to add support for additional ggplot2 geoms.

Improvements

• Improved Braille bit mapping for more accurate scatter and line plots
• Better color handling for multi-group aesthetics
• Fixed issues with quosure parsing in aesthetic mappings
• Fixed axis label formatting (0 now displays as “0”, not “0.0e+0”)
• Fixed border overlap issue - data no longer appears on/within borders
• Fixed is_braille error with ANSI color codes

Documentation

• Comprehensive vignette: “ggplotcli: Universal ggplot2 to Terminal Plotting”
