Hi,
I'm writing a function that needs the input names (as characterstrings) as part
of the output.
With deparse(substitute( ) ) that works fine, until I replace all zeros with
0.001 (log is calculated at some time):
tf <- function(input) { input[input==0] <- 0.001 ; deparse(substitute(input))
}
myguess <- 42
tf(myguess) # not "myguess", but "42"
Now when I extract the input names before replacing the zeros, this works:
tf <- function(input) { out <- deparse(substitute(input)) ; input[input==0]
<- 0.001 ; out }
tf(myguess) # correct: "myguess"
myguess <- 0 ; tf(myguess) # ditto
While I did find a workaround, I'm still wondering why this happens.
Any hints on where to start reading?
Thanks ahead,
Berry
