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
