# Getting Started with ggguides

## Overview

ggguides simplifies common legend operations in ggplot2. Instead of memorizing theme element names and their nested structure, you can use intuitive one-liner functions to position, style, and manage legends.

Key features:

- Position legends with `legend_left()`, `legend_right()`, `legend_top()`, `legend_bottom()`, `legend_inside()`

- Style legends with `legend_style()` for fonts, backgrounds, and borders

- Wrap legend entries with `legend_wrap()` for multi-column layouts

- Collect legends from patchwork compositions with `collect_legends()`

## Installation

    install.packages("ggguides")

Or the development version from GitHub:

    # install.packages("pak")
    pak::pak("gcol33/ggguides")

## Basic Usage

Let’s create a simple plot to demonstrate the legend helpers:

    p <- ggplot(mtcars, aes(mpg, wt, color = factor(cyl))) +
      geom_point(size = 3) +
      labs(color = "Cylinders")

    p

### Moving the Legend

Position the legend on any side with a single function call:

    p + legend_left()

    p + legend_bottom()

### Inside Positioning

Place the legend inside the plot area using coordinates or shortcuts:

    p + legend_inside(position = "topright")

    p + legend_inside(x = 0.02, y = 0.98, justification = c("left", "top"))

### Removing the Legend

    p + legend_none()

## Styling Legends

Use `legend_style()` to customize the legend appearance:

    p + legend_style(size = 14)

    p + legend_style(
      size = 12,
      title_size = 14,
      title_face = "bold",
      background = "#FFF3E0",
      background_color = "#FF9800"
    )

## Wrapping Legend Entries

For legends with many entries, use `legend_wrap()` to create multi-column layouts:

    ggplot(mpg, aes(displ, hwy, color = class)) +
      geom_point() +
      legend_wrap(ncol = 2)

## Combining Functions

ggguides functions compose naturally with the `+` operator:

    ggplot(mpg, aes(displ, hwy, color = class)) +
      geom_point() +
      legend_left() +
      legend_style(size = 12, title_face = "bold", background = "#FFF3E0")

    ggplot(mpg, aes(displ, hwy, color = class)) +
      geom_point() +
      legend_wrap(ncol = 2) +
      legend_bottom()
