I'd like a function that returns the variable name.
As in:
MyData$Var1
Would return:
Var1
Not quite sure what you mean, but does this get you started?
nn <- function(x) deparse(substitute(x))
str( z <- nn(airquality$Month) )
# chr "airquality$Month"
## Not sure what now - maybe:
strsplit(z, "$", fixed = TRUE)[[1]][-1]
# [1] "Month"
You'll have to figure out with a variable called foo$bar$baz and with
airquality["Month"] etc.
Hope this helps a little.
