How to rename a single column in an R data frame?

We can do this by defining the newname as shown below −

> Samp <- data.frame(sample(1:100,10))
> Samp
  sample.1.100..10.
1 47
2 63
3 57
4 16
5 53
6 7
7 54
8 2
9 13
10 14
> colnames(Samp) <- "Sampled Values"
> Samp
  Sampled Values
1 47
2 63
3 57
4 16
5 53
6 7
7 54
8 2
9 13
10 14

Since we only have one column in the data frame, so it is sufficient to use the object name.
