Hi, I have been getting out of memory errors with RBloomberg and now Rbbg. I'd like to manually fix the package but I cannot get my hand on the source code, except on an old fork found on github. Could someone point me where I can the latest source? Standard package download within R with type source is not working and findata.org seems to be dead following the package name change. Regards, Alexandre
Rbbg Java out-of-heap-space error (potential cause: response_cache)

Dear all, Does anyone have the RExcel 3.2.1.0 file? I tried to download from internet but I could only get a .tar file, which I don't know how to install. Thanks very much JJ
Alexandre, The Java side of the Rbbg package caches all data responses during a session. That's probably what's responsible for the memory issues you're experiencing. This is a known bug that I haven't had a chance to fix, but if you'd like to submit a patch I would happily accept. The latest source is on my github at http://github.com/johnlaing/blpwrapper. (I assume the "old fork" you refer to is Jeff Davis's version, tweaked to work on Linux.) The findata.org site hosts Windows binaries, so you should not specify type = "source" from within R. This works just fine: install.packages("Rbbg", repos = "http://r.findata.org") -John On Wed, Jun 20, 2012 at 4:23 AM, Alexandre CESARI

John, Thanks for the info. I tested a slightly different version and that seems to work for me. I don't know much about the BBG api but what I did was simply to store the last reponse rather than adding it into an array. Given the code, I'm not sure that caching is all that useful. Alexandre
