...w the information about how to join the bugzilla site was not available at bugzilla and buried in the CRAN web site instructions on reporting bugs (which pointed me at Bugzilla and not the page you showed me). The example is pretty minimal.? I left the tracing statements (flog.trace()) and the toJSON, fromJSON in as I thought they might provide some context for another method of approaching my problem. It looks like I'm getting better results using socketConnection() rather than read.socket(), so I'll pursue that solution (but still file a bug report, as it seg faults are never good...

But I just want the last elemen to be hightlighted. The following code is not working:
