I am still struggling to map a character string to an object name and
vice versa in R.
I thought the as.name() function might work, but observe the following
behaviour ...
> attach(warpbreaks)
> levels(tension)
[1] "L" "M" "H"
> levels(as.name("tension"))
NULL
> objectname<-as.name("tension")
> objectname
tension
> levels(objectname)
NULL
So even though it sets up a symbol, this symbol isn't recognised as an
object name by functions such as levels().
I need 2 functions, call them A and B such that A("tension") yields the
object name tension which is recognised by functions and
B(tension) yields the character result "tension".
Any suggestions would be greatly appreciated,
Philip
