exists() and functions
...t I'm doing tests in the main
environment to figure out the function, so the variables DO exist in
the parent environment of a function call.
Why does:
myfunction <- function(variable_outside_function)
{
print(exists("variable_outside_function",inherit=FALSE))
print(exists("another_variable_outside_function",inherit=FALSE))
}
myfunction()
Return:
[1] TRUE
[1] FALSE
I didn't assign anything to variable_outside_function, so I'm unclear
why it thinks it exists...
