[R] clipping viewports

[Mikkel Grum]

Dear useRs,

Why are the rotated blue and yellow boxes in the example below clipped outside of 6 x 6 inch window in the middle of the page?? Where does the 6 x 6 inch window come from? I would like to make use of the entire page.

> library(grid)
> pdf(file = "FarmMaps.pdf", paper = "a4")
> pushViewport(viewport(
+    width = unit(7.6, "inches"), height = unit(11, "inches"), clip = "off"))
> grid.rect(gp = gpar(col = NA, fill = "grey"))
> pushViewport(viewport(x = unit(3.6, "inches"), y = unit(3.6, "inches"),
+    width = unit(3.6, "inches"), height = unit(3.6, "inches"), clip = "off",
+    angle = 76))
> grid.rect(gp = gpar(col = NA, fill = "blue"))
> upViewport()
> pushViewport(viewport(x = unit(1.8, "inches"), y = unit(7.6, "inches"),
+    width = unit(2.6, "inches"), height = unit(2.6, "inches"), clip = "off",
+    angle = -56))
> grid.rect(gp = gpar(col = NA, fill = "yellow"))
