[R] WinBUGS14 and R

[Uwe Ligges]

Try to use paths without blanks in it.
If that does not work, please provide some reproducible example (e.g., I 
do not have "abs.4diff").


BTW: "(is greyed out)" means cannot be used now (buttons appear greyed 
out in the GUI). Hence the error happened before (in the check line).
