Description
Save Incremental Builds of Plots.
Description
Saves a 'ggplot' object into multiple files, each with a layer added incrementally. Generally to be used in presentation slides. Flexible enough to allow different file types for the final complete plot, and intermediate builds.

ggbuildr
ggbuildr is a simple tool for saving incremental "builds" of a ggplot object. Intended use-case is to save plots for presentation slides.
Installation
To install from GitHub:
# Currently only available as development version from Github
# install.packages("devtools")
devtools::install_github("jongbinjung/ggbuildr")
Usage
library(ggplot2)
library(ggbuildr)
set.seed(1)
X <- rnorm(20)
Y <- X + rnorm(20)
pd <- data.frame(X, Y)
p <- ggplot(pd, aes(X, Y)) +
geom_smooth() +
geom_point(shape = 21, size = 2,
fill = "white", color = "black") +
# Fixing the limits ensure plot ranges are constant
coord_cartesian(xlim = c(-2.5, 2), ylim = c(-4, 4))
# Plot smooth, and then point
build_plot(p, build_order = list(1, 2))
# Plot point, and then smooth, but preserve order (i.e, keep points on top)
build_plot(p, build_order = list(2, 1))
# Plot point, and then smooth, and draw smooth layer on top of point
build_plot(p, build_order = list(2, 1), preserve_order = FALSE)
