Write an R program to change the first level of a factor with another
level of a given factor.
V1 = c("a", "b",
"a", "c", "b")
print("Original vector:")
print(V1)
f1 = factor(V1)
print("Factor of the said vector:")
print(f1)
levels(f1)[1] = "e"
print(f1)
OUTPUT
> V1 = c("a", "b", "a", "c",
"b")
> print("Original vector:")
[1] "Original vector:"
> print(V1)
[1] "a" "b" "a" "c" "b"
> f1 = factor(V1)
> print("Factor of the said vector:")
[1] "Factor of the said vector:"
> print(f1)
[1] a b a c b
Levels: a b c
> levels(f1)[1] = "e"
> print(f1)
[1] e b e c b
Levels: e b c
