Change Row name of a particular Column in Dataframe

How to change Row name of a particular column in R dataframe:

<df

Name    Value
A       10
B       20
C       30

I want output to be:

Name    Value
AAA     10
BBB     20
CCC     30

I have tried data.table library but it couldn't work.

library(data.table)
my_df <- setattr(df$Name, "row.names", c("AAA", "BBB", "CCC"))

Looks like the name column is it's own column. See the code below

sample <- data.frame(Name = c("A", "B", "C"), Value = c(10,20,30))

Looks like this: 

  > sample
 Name Value
1    A    10
2    B    20
3    C    30

Now Try:

sample$Name <- c("AAA", "BBB", "CCC")

Yields: 

> sample
  Name Value
1  AAA    10
2  BBB    20
3  CCC    30
