That helped. I continued to have issues with
draw.in=vplayout(2,2)$name
(I guess I still don't understand it use), but the following positions
the plot on the grid where I want it.
grid.newpage()
pushViewport(viewport(layout=grid.layout(2,2)))
vp <- vplayout(2,2)
pushViewport(vp)
print(p,newpage=FALSE)
upViewport()
The reason the ggplot instances just worked is that the ggplot2 package
is doing the viewport traversal for me in ggplot2::print.ggplot.
Thanks for the help!

The problem is that you have not pushed your viewport so it doesn't
exist in the plot. (You only pushed the layout viewport).
grid.ls(viewports = TRUE)
ROOT
GRID.VP.82
Try this:
vp<- vplayout(2,2)
pushViewport(vp)
upViewport()
grid.ls(viewports = TRUE)
#ROOT
# GRID.VP.82
# GRID.VP.86
print(p, newpage = FALSE, draw.in = vp$name)

Error in grid.Call.graphics("L_downviewport", name$name, strict) :

What am I doing wrong?
Thanks!
