Combine base and ggplot graphics in R figure window
I'd like to plot side by side a plotrix graphic and a ggplot2 graphic. how could I do ?
Below is an unsuccessful attempt (gg1
does not appear in the figure).
library(ggplot2)
library(gridExtra)
library(plotrix)
Mvalues <- matrix(rpois(9,1), ncol=3)
Mcolors <- matrix(rpois(9,5), ncol=3)
g1 <- color2D.matplot(x=Mvalues, show.values=2, cellcolors=Mcolors,
xlab="x", ylab="y", axes=FALSE, vcex=0.4)
gg1 <- grob(g1)
gg2 <- ggplot(diamonds, aes(clarity, fill=cut)) + geom_bar(position="dodge")
grid.arrange(gg1,gg2,ncol=2)
