Clearly you don't have cairo installed or functional, since the preferred
versions of these devices do not use X11, and do trap this error.
tiff("a.tiff", units = "in", res = 1200)
Error in tiff("a.tiff", units = "in", res = 1200) :
unable to start device 'tiff'
In addition: Warning message:
In tiff("a.tiff", units = "in", res = 1200) : cairo error 'out of memory'
There is nothing new here (Xlib-based devices would crash with
insufficient memory 'for ever'), but we will see if we can trap this.

I love the new tiff(), jpeg(), and png() in R 2.7.0 but found
an issue that I didn't see reported.
When specifying 'units = "in"' but forgetting to change the
default height and width (so the figure is unintentionally
going to be 480 inches by 480 inches) I run into problems.
Here's the reproducible example:
tiff("a.tiff", units = "in", res = 1200,
compression = "lzw")
hist(rnorm(10))
dev.off()
Before dev.off(), I get these warnings:
Warning messages:
1: In title(main = main, sub = sub, xlab = xlab, ylab = ylab,
... :
X11 protocol error: BadAlloc (insufficient resources for
operation)
2: In title(main = main, sub = sub, xlab = xlab, ylab = ylab,
... :
X11 protocol error: BadDrawable (invalid Pixmap or Window
parameter)
and the dev.off() line will give me:
*** caught segfault ***
address 48, cause 'memory not mapped'
Traceback:
1: dev.off()
Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace
