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.<br>

Yes, I think that is the implication. The basic desire is to be able to store the output in a variable (which might possibly be manipulated) and then print it out or embed it in a file later.<div><div></div><div class="h5">

Now if you call tikz with an empty file name<br>
<br>
tikz('')<br>
<br>
it will dump to the console. It cant be called with no file name<br>
because that will default to the standard Rplots.tex file. The changes<br>
are on Github.<br>
<br>
As for the rawConnection functionality, I do not know much about this<br>
sort of R programming but I suppose it would be possible. Am I right<br>
in thinking that afterward you might then<br>
<br>
print(rc)<br>
<br>
to output to a file? It would certainly not be trivial on the C level<br>
but I believe it could be done.<br>
