Hi everyone,
I'd like to report a similar experience. When I attempt to run the first
CFA example in bootSem(), specifically the line:
system.time(boot.cnes <- bootSem(sem.cnes, R=100, Cov=hcor, data=CNES))
R crashes and I get a notice about X11. I copied my sessionInfo() below.
Any ideas for a workaround?
Thanks
Eric
