[R-lang] fixing R for Linux bug

[Lngmyers]

This may not be the most exciting post to start R-lang off with, but I 
think that some of the founders of the list are Linux users, and maybe 
they can help me debug a project involving linguistics statistics in R.

(Warning: This post definitely belongs in the "advanced" category....)

Some of you may know about my MiniJudge project, a JavaScript (and soon 
Java) based tool for designing, running, and analyzing simple syntactic 
judgment experiments:

http://www.ccunix.ccu.edu.tw/~lngproc/MiniJudge.htm

Since the judgments are collected as traditional binary yes/no 
judgments, the analysis involves generalized linear mixed effect 
modeling (GLMM). GLMM is too complex for me to program in any ordinary 
language (though I've got somebody working on this). So I use the 
JavaScript to write R code.

This R code works fine in Windows and Mac versions of R, but not in the 
Linux version, apparently due to differences in how line breaks are 
handled, and maybe also differences in how big the clipboard is for 
pasting code into Linux R. Since I don't use Linux enough to be 
comfortable in it, I was hoping somebody could help out by quickly 
testing the MiniJudge R code and giving top-of-the-head advice.

To test, get the data file from here:

http://www.ccunix.ccu.edu.tw/~lngproc/demo.txt

Then go to here to generate the R code (entering "demo.txt", without 
quotation marks of course, and clicking "OK"):

http://www.ccunix.ccu.edu.tw/~lngproc/MiniJudgeJS.htm#genRcode

Select the code from the text area and paste into R. Since it might be 
too large for Linux R's clipboard, you can also try pasting in bits of 
it at a time. I think it all works except for the line breaks thing. I 
wrote this before I learned about the "@coefs" trick for extracting the 
coefficients matrix in lmer outputs, so to find the coefficients in the 
lmer output I first "sink" it into a file, then read it back in as a 
character string and search for it! Kind of stupid, but I need to save 
the analysis output anyway. Still, I'm not sure that this sink-and-read 
procedure is the crucial problem...?

If all works well, the code should generate a text file called 
"demo_analysis.txt", which looks like this:
