I have added "C:\Program Files\Java\jre1.6.0_03\bin\client" to the PATH variable to get rJava working. However, the following error message results after inputting 'li...

Hi Hilmar, weird. The memory problem seems be due to recursion (my R, version 3.3.3, says: Error: evaluation nested too deeply: infinite recursion / options(expressions=)?, just write traceback() to see how it happens), but why does it segfault with xlsx? Nb xlsx is the culprit: neither rJava nor xlsxjars cause the problem. On the other hand, quick googling for r+xlsx+segfault returns tons of reports of how xlsx crashes in dozens of situations. See for example http://r.789695.n4.nabble.com/segfault-in-gplots-heatmap-2-td4641808.html. Also, the problem might be platform-specific. It would be interes...
