It means that you have some data in your `veh_value` vector that `log`
/ `smooth.spline` is choking on.
For instance, are there negative numbers in `veh_value`?
R> log(-2)
[1] NaN
Check the other possibilities, like the existence of NA, or Inf values
(use `is.na` and `is.infinte`)
Examine both `veh_value` and also the result of log(veh_value).
HTH,
