f1 <- factor(sample(LETTERS, size=6, replace=TRUE))
f2 <- factor(sample(LETTERS, size=6, replace=TRUE))
print("Original factors:")
print(f1)
print(f2)
f = factor(c(levels(f1)[f1], levels(f2)[f2]))
print("After concatenate factor becomes:")
print(f)

Sample Output:

[1] "Original factors:"
[1] Q Y M J J H
Levels: H J M Q Y
[1] B J L S F Z
Levels: B F J L S Z
[1] "After concatenate factor becomes:"
 [1] Q Y M J J H B J L S F Z
Levels: B F H J L M Q S Y Z
