Can WinBUGS run two processes through R at the same time?
...essage appears while I put the code to run for the second
WinBUGS.
The error message:
Error in file(file, ifelse(append, "a", "w")) :
cannot open the connection
In addition: Warning message:
In file(file, ifelse(append, "a", "w")) :
cannot open file 'inits1.txt': Permission denied
Can WinBUGS run two processes through R at the same time?
If it can, how should I modify the setting to do this?
Thanks.
