Dear List,

does the R module work? To be more specific "m-r.tex". I tried to 
run the test named as "Johan's test file" and got the result below

--------------------

! Undefined control sequence.

system          > tex > error on line 20 in file /home/erik/tmp/Glockner/t.tex: Undefined control sequence ...

10     
11     \starttext
12     
13     First a test of whether the workspace is persistent:
14     bla
15     
16     \startR
17     a <- "bla"
18     b <- "blabla"
19     ls()
20 >>  \stopR
21     
22     One \R run ends, another begins.
23     
24     \startR
25     ls()
26     \stopR
27     
28     Now follows a hidden \R run which cleans the R workspace
29     
30     \startRhidden

\Rfile ^@-\TEXbufferfile 
                        {\Rbufferprefix \nofRfiles }
<argument> texmfstart --ifchanged=\Rfile 
                              \space --direct R CMD BATCH -q --save --restore \
\executesystemcommand #1x-\ctxlua {os.execute([[#1
                                                  ]])}
\stopR #-\doifmode {*\v!first }\runR 
                                     \typefile {\Rfile .out}
l.20 \stopR
