Using variable value as column name in data.frame or cbind

Question

Is there a way in R to have a variable evaluated as a column name when creating a data frame (or in similar situations like using cbind)?

For example

Answer 1

> d <- setNames( data.frame(a=1:10), a)
> d
   mycol
1      1
2      2
3      3
4      4
5      5
6      6
7      7
8      8
9      9
10    10
