FWIW the restriction is only on the console input - if you send it directly, there is no limit (I have never heard of nuiton-j2r but if you use rJava to interface from Java to R there is no limit - the string you parse+evaluate can be of any length). Hi Simon,

nuiton-j2r is in fact an abstraction layer to rjava or rserve so that it can switch between one or other implementation using simple configuration (http://maven-site.nuiton.org/nuiton-j2r/ sorry but this is in french). And in fact I encounter the problem using it. What is done is basically creating the R instruction from java and sending it to R using the eval method from the Rengine object (as we use jri in this specific application). The R instruction should create an object a of class morris, and I try then to get back the a$X object (the X item of the morris object) but I get back a null object without any reason, that is why I tried copying the instruction directly in R and thus getting this problem. So that is strange if you say that there is no limit using rjava/jri. Cheers, Jean

Cheers, Simon

Thanks for your time Duncan,

I join here the instruction that is not correct, hoping that might help you. The file is encoded in utf-8 so you should not have any problem reading it.

I doubt to that it is an R bug too, but with all my tests i am less and less sure of that.

I have no problem sourcing that file, but I do get an error if I try to cut and paste it, because it's a single line of 4890 characters, and that's too long. So this is an R limitation, but it's one with an easy workaround: just add some line breaks into your source.

Your message has encoding problems, so it's not readable. Could you put the code online somewhere where we could download it in its original form? I doubt if this is an R bug, but I can't point out the problem in your code (or confirm that it really is an R bug) without an undamaged copy of the code.
