Hello,
I'm enjoying the fun (self-imposed) task of learning Python, RPy2 and
PyGTK all in one go, so this question may be partly due to my general
status as a newbie. My application will have an embedded console in it.
Everything is generally working nicely, however I've noticed that if I
load a particularly large data file via R's read.delim() command, Python
chokes on the output. The data is loaded as expected, but when I try to
print the output to the console, only a portion of the data.frame is
printed (~65000 characters), presumably because it reached the maximum
string size, and then a seemingly-unrelated GTK widget breaks (but we'll
ignore that part for now)
What seems ideal to me would be a way to grab the R console output one
line at a time rather than all at once so I can just append those lines
individually to my gtk text buffer. I can easily do this for a specific
task, such as only for a data.frame, programmatically break it apart by
rows. However, I'm hoping for something more general that could apply to
any output.
I have tried to set robjects.rinterface.setWriteConsole(f) to some
function f that just appends to a buffer, but that console callback
function doesn't seem to append anything to the buffer if I do a call to
robjects.r("some command here"). That said, I'm not sure how this method
works exactly and if I'd encounter the same problem because a single
string of the entire output would just be appended to the buffer.
Ok that was a bit long-winded. Is there an obvious solution to this
problem that I'm missing? Am I not being clever enough?
Thanks for your help,
brandon
