The condition to determine if the calculation can be done is a if-clasue (i.e. if(m>0). Unfortunately, when m is missing, the program crashed. Just wonder who can help me out.
1. Please ask questions on R-help after reading its posting guide.
R-devel is for development purposes.
2. Your code results in an ERROR rather than a crash.
3. Check if m exists before you compare it to some value.
