[R] Error while running Vegas function in cpvSNP package

Hello,

Please find attached a script where I tried to replicate the issue. I was
unable to reproduce the error. Perhaps you can send me more details?

Also, it appears the LD matrix you are using is not symmetric nor does it
have 1's on the diagonal. Both of these things should be satisfied for the
algorithm to work properly.

Feel free to let me know if you continue to run into errors.

Thanks,
Caitlin
