xkcdline: Draws handwritten lines

Description

This function draws ggplot2 segments or circles in a handwritten style.

Usage

xkcdline(mapping, data, typexkcdline = "segment", mask = TRUE, ...)

Arguments

mapping

Mapping between variables and aesthetics generated by aes. See Details.

data

Dataset used in this layer.

typexkcdline

A string value. If it is segment, it draws a segment. If it is circunference, it plots a circunference.

mask

Logical. If it is true, it erases the pictures that are under the line.

...

Optional arguments.

Value

• A ggplot layer.

Details

It draws a segment or a circunference in a XKCD style. If it is a segment, the following aesthetics are required:

1. xbegin: x position of the point from.
2. ybegin: y position of the point from.
3. xend: x position of the point to.
4. yend: y position of the point to.

If it is a circunference, the following aesthetics are required:

1. x: x position of the center.
2. y: y position of the center.
3. diameter: diameter of the circunference.

Additionally, you can use the aesthetics of geom_path, pointssegment and pointscircunference.

Examples

data <- data.frame(x1=c(1,2), y1=c(10,20), xend=c(2.5,0.5),
yend=c(20,10), model=c("low","high"))

ggplot() + xkcdline(mapping=aes(xbegin=x1 +y1, ybegin=y1, xend =xend, yend= yend,
color = model), data=data)

ggplot() + xkcdline(mapping=aes(xbegin=x1 +y1, ybegin=y1, xend =xend, yend= yend,
color = model), data=data) + facet_grid(. ~ model)

ggplot() + xkcdline(mapping=aes(x=x1 +y1, y=y1, diameter =xend), data=data, type="circunference")
