Hi, I solved the crashing issue by removing references to tclck. Here is a gist that shows the edits: https://gist.github.com/ericpgreen/6926595
However, I am getting an error about convergence failures: Error in bootSem2(sem.cnes, R = 100, Cov = hcor, data = CNES) : more than 10 consecutive convergence failures As described in my previous message, I am trying to run the first example in ?semBoot, not my own data. The only difference from the example is that I call the modified bootSem2() function I created by commenting out references to tclck. Increasing max.failures does not seem to help. I'm not sure what is going on, but I think this example should work fine. Eric On Thursday, October 10, 2013 at 3:01 PM, Eric Green wrote: > Hi everyone, > > I'd like to report a similar experience.
