[Tikzdevice-bugs] Single file with tikzDevice

[Gabor Grothendieck]

Just thought I would add that there seemed to be a lot of interest in the
connection feature on that r-devel thread and since no other device can
output to an R variable (other than by writing out a file and reading it
back in) it might be that some users would use tikzDevice for this feature
alone regardless of whether it was implemented in terms of connections or
otherwise.
