[datatable-help] example(data.table) confusing use of "v"

[Arunkumar Srinivasan]

The ‘v’ in `v <- ‘x’` bears no relation to column name ‘v’. I understand how/why this can be confusing. Perhaps we should rename that to `keycol <- ‘x’` or something like that.. Please file an issue, and even better as a PR.

In the *Example* section of data.table-package documentation, `v` is used as  
a column name, and later a variable `v`<-"X" is defined and used in  
setkeyv(DT,v) to set the key to column `x`. Then `v` is again used as column  
name. This is confusing to me. Is the double use of `v` as both column name  
and variable intentional? See the extract of the Examples section below:
