Hi Rick,

I don't think I ran any processing in between - I'm almost positive it was right away.

I just used the setenv AFNI_NOMMAP YES command and then ran rPkgsInstall -pkgs ALL (both in the same window and in a new window), and still get the same error:

[OBYL100MAC:~] canlabuser% rPkgsInstall -pkgs ALL

*** caught segfault ***
address 0x0, cause 'memory not mapped'

Traceback:
1: .Call("R_SUMA_HistString", ExecName, args, ohist)
2: AFNI.command.history(ExecName, args, NULL)
3: read.rPkgsInstall.opts.batch(args, verb = 0)
An irrecoverable exception occurred. R is aborting now ...
Segmentation fault

Not sure what is wrong...
