It is possible to create inset graphs?
ggplot2, graphics, insets, r
Solution
Section 8.4 of the book explains how to do this. The trick is to use the `grid` package's `viewport`s.
#Any old plot
a_plot <- ggplot(cars, aes(speed, dist)) + geom_line()
#A viewport taking up a fraction of the plot area
vp <- viewport(width = 0.4, height = 0.4, x = 0.8, y = 0.2)
#Just draw the plot twice
png("test.png")
print(a_plot)
print(a_plot, vp = vp)
dev.off()
Problem
I know that when you use `par( fig=c( ... ), new=T )`, you can create inset graphs. However, I was wondering if it is possible to use ggplot2 library to create 'inset' graphs. UPDATE 1: I tried using the `par()` with ggplot2, but it does not work. UPDATE 2: I found a working solution at ggplot2 GoogleGroups using `grid::viewport()`.
