Assessing the name of an object within an argument
?
You can get that using `formals()`.
my_func <- function(dataset = iris)
{
? #print(dataset) # here I do not want to print the dataset but the name
? # of the object - iris in this case - instead
? print(formals()$dataset) # this is what you want
}
This gives you what the arguments were as an alist. It won?t always be a name, of course, but when it is, as in this case, that will be a symbol you can print.

Hi All,
I have a function like
my_func <- function(dataset)
{
some operation
}
Now I would like not only to operate on the dataset (how this is done is
obvious) but I would like to get the name of the dataset handed over as an
argument.
Example:
my_func <- function(dataset = iris)
{
print(dataset) # here I do not want to print the dataset but the name
of the object - iris in this case - instead
# quote() does not do the trick cause it prints "dataset" instead of
"iris"
# as.name() gives an error saying that the object can not coerced to a
symbol
}
Is there a way to do this?
Kind regards
Georg
