With grid.arrange I can arrange multiple ggplot figures in a grid to achieve a multi-panel figure by using something like:
generate some ggplot2 plots, then
plot5 <- grid.arrange(plot4, plot1, heights=c(3/4, 1/4), ncol=1, nrow=2)
How can I obtain an 'unbalanced' 2 col layout with one plot in the entire first col and three plots in the second col? I toyed with a 'grid-of-grids' approach by trying to use grid.arrange to plot one grid (e.g. plot5, above) against another plot, but obtained:
Error in arrangeGrob(..., as.table = as.table, clip = clip, main = main, : input must be grobs!
