[R] gridBase Base Plot Positioning

[Dario Strbenac]

Hello,

I'm trying to follow the documentation of how to use gridBase, and I've reached the minimal code example below as my best effort. Can someone explain how to keep the column of boxplots on the same page as the rectangles (even though I've tried new = TRUE) ? Also, would it be hard / possible to match up the middle of each boxplot to the middle of each rectangle ?

pdf("tmp.pdf", h = 6, w = 10)
pushViewport(plotViewport(c(5, 5, 4, 2)))
pushViewport(viewport(layout = grid.layout(4, 6)))
for(i in 1:5)
{
    for(i2 in 1:4)
    {
        pushViewport(viewport(layout.pos.row = i2, layout.pos.col = i))
        grid.rect()
        popViewport()
    }
}
pushViewport(viewport(layout.pos.col = 6))
plot.new()
par(plt = gridPLT(), new = TRUE)
randData <- lapply(1:4, function(x) sample(10, 10, TRUE))
boxplot(randData, horizontal = TRUE)
dev.off()

I'm using gridBase_0.4-3.

Thanks,
       Dario.
