I am trying to plot a smoothing spline to using the following code, and an
error pops up:
> car <- read.table("car.csv",sep=",",header=T)
> attach(car)
> names(car)
[1] "veh_value" "exposure" "clm" "numclaims" "claimcst0" "veh_body"
[7] "veh_age" "gender" "area" "agecat" "X_OBSTAT_"
> plot( log(veh_value), claimcst0, ylim=c(0,10000))
> smooth.spline( log(veh_value), claimcst0)
Error in smooth.spline(log(veh_value), claimcst0) :
NA/NaN/Inf in foreign function call (arg 3)
### What does this error mean> I do not get it??
