Dear R Users,
I've got a strange problem, which I do not really understand:
when I use na.spline from the zoo package, the option na.rm is just being
ignored, see this adjusted example from the na.spline help page:
########################
d0 <- as.Date("2000-01-01")
z <- zoo(c(NA, 11, 13, NA, 15, NA), d0 + 1:6)
na.spline(z)
na.spline(z, na.rm = FALSE)
na.spline(z, na.rm = T)
#######################
In all 3 cases, the output looks like this with the trailing NA being
replaced:
2000-01-02 2000-01-03 2000-01-04 2000-01-05 2000-01-06 2000-01-07
8.333333 11.000000 13.000000 14.333333 15.000000 15.000000
Am I missing something here?
Any help is very much appreciated...
Thanks,
Katharina
