I have a function, that just do a print, mytable
is a global variable
f <- function(field){ print(mytable[mytable$a == field,]) }
My problem is that this function is called (not by me, it is sent as command to R by another process like an editor) as f(EXAMPLE)
, f(EXAMPLE2)
... this fails because EXAMPLE
is not a defined variable, I would like EXAMPLE
to be "EXAMPLE"
(a string).
What can I do in the function f
for field
to have the value "EXAMPLE" when f(EXAMPLE)
is evaluated ?
I realize that this is very convoluted...
You can use deparse(substitute(yourobject))
:
R> deparse(substitute(foo))
[1] "foo"
