addIMGtopanel: Add images to a ggplot facet plot

In UW-Upwelling-Project/imageryML: Functions for Machine Learning with Oceanographic Imagery

Description

This adds images in a image list to the panels in a ggplot object.

Usage

addIMGtopanel(p1, img.list, pal = colorRamps::matlab.like(100))

Arguments

p1	A ggplot object with panels, i.e..
img.list	A list of images for each center. Image 1 goes with panel 1, etc. Panels are numbered across rows. Image are recycled if the list is shorter than the number of panels.
pal	The color ramp for the images. This will determine what the images look like.

Examples

img.list <- list()
for(i in 1:3) img.list[[i]] <- raster::as.raster(matrix(stats::runif(4),2,2))

library(ggplot2)
p <- ggplot(mtcars, aes(x=mpg, y=hp)) + geom_line() + facet_wrap(~cyl)

addIMGtopanel(p, img.list)


#In this example, the images are cut off at the top.
p <- ggplot(mtcars, aes(x = mpg, y = wt)) + geom_point() + 
     facet_grid(vs + am ~ gear, margins = TRUE)

addIMGtopanel(p, img.list)
