  gglayout(plotList,
    layout = grid.layout(1, length(plotList)),
    colwise = TRUE, rowwise = !colwise)

`plotList`	A `list` of `ggplot` objects
`layout`	A layout provided by `grid.layout`

The plotsin plotList are printed sequentially to the viewports defined by layout, in order of rows followed by columns. If an element of plotList is NULL, then that plot is empty.

require(ggplot2)
require(grid)
p <- ggplot(mtcars, aes(factor(cyl)))
pList <- list(
    p + geom_bar(),
    NULL,
    p + geom_bar() + coord_flip(),
    p + geom_bar(fill="white", colour="darkgreen")
)

gglayout(pList)
gglayout(pList, layout=grid.layout(4, 1))
gglayout(pList, layout=grid.layout(1, 4))
gglayout(pList, layout=grid.layout(2, 2), rowwise=TRUE)
