[R] Line numbers of scan(0

[Lisa]

Dear all,

Does everyone know how to change the line numbers of scan()? For example,

> scan(n = 3)
1: 4	
2: 6
3: 9
Read 3 items
[1] 4 6 9

I just want to change the line numbers 1, 2, and 3 to, say a, b, and c that
look like this:

> scan(n = 3)
a: 4	
b: 6
c: 9
Read 3 items
[1] 4 6 9

Any help will be appreciated. 

Lisa
