How to convert variable (object) name into String [duplicate]
I have the following data frame with variable name "foo";
> foo <-c(3,4);
What I want to do is to convert "foo" into a string. So that in a function
I don't have to recreate another extra variables:
output <- myfunc(foo)
myfunc <- function(v1) {
# do something with v1
# so that it prints "FOO" when
# this function is called
#
# instead of the values (3,4)
return ()
}
You can use deparse and substitute to get the name of a function argument:
myfunc <- function(v1) {
deparse(substitute(v1))
}
myfunc(foo)
[1] "foo"
