Can anyone show me how to refer to an object name that is passed to a
function, from within the function?
deparse(substitute(x))
For example:
MyModel <- 1
test <- function(x) {
if(x == 1) {cat("x is a valid object.\n")}
}
test(x)
Well you don't want to test(x) since x has not been defined. You wnat
to test(MyModel)
MyModel <- 1
test <- function(x) {xname <- deparse(substitute(x))
if(x == 1) {cat(xname, " is a valid object.\n")}
}
test(MyModel)
#MyModel is a valid object.
What I would like this to do is pass MyModel to function test, and
if it
passes a test, be able to print "MyModel is a valid object."
Thanks.
