If the resulting order isn't what you want, you can sort afterwards. If you name the arguments to expand.grid, they will become column names:
df = expand.grid(a = a, b = b)
df[order(df$a), ]
And expand.grid generalizes to any number of inp...
Why does @foo.setter in Python not work for me?

Compare two files line by line and generate the difference in another file
