thanks for reporting this. We've seen this problem before with the vcd
package. The reason is that the default background is usually
"transparent" whereas for jpeg() and png() devices it is "white". That has
the effect that the
command at the end of node_boxplot() not only draws the bounding rectangle
but also fills it with "white", thus hiding the actual boxplots. The fix
is to use
grid.rect(gp = gpar(fill = "transparent"))
instead. We'll commit a fixed party to CRAN asap.
