How to findout the name of a dataframe
Will this work for you:
myFunc <- function(var){
+ # get the dataframe name
+ charName <- deparse(substitute(var))
+ # parse out data.frame
+ dataFrame <- sub("\\$.*", "", charName)
+ cat("input:", charName, "data.frame:", dataFrame, "\n")
+ }
myFunc(mydata$V1)
input: mydata$V1 data.frame: mydata

Let'say we have a dataframe mydata with column v1. If mydata$v1 is passed
to a function, is there way, then, to extract the name of the dataframe?
What I now do is passing the name of the dataframe to the funcion, so
passing two parameters. Maybe with mydata$v1 it is not possible, but with
mydata['v1'] or mydata[,'v1'] it is?
Thanks
