The example doesn't match the description
The description:
"The following example starts with the year/ month/day numbers for the third Wednesday in January of several years and then combines them all into Date objects:"
The example: ( note the dates doesn't look like 3rd Wed of Jan
years <- 2010:2014
months <- rep(1, 5)
days <- 5:9
ISOdate(years, months, days)
#> [1] "2010-01-05 12:00:00 GMT" "2011-01-06 12:00:00 GMT"
#> [3] "2012-01-07 12:00:00 GMT" "2013-01-08 12:00:00 GMT"
#> [5] "2014-01-09 12:00:00 GMT"
as.Date(ISOdate(years, months, days))
#> [1] "2010-01-05" "2011-01-06" "2012-01-07" "2013-01-08" "2014-01-09"
by the way, description here is matching with the example in the first edition of this book.

last paragraph |
in the last paragraph:
"We can use the zoo function na.approx to fill our missing values using a cubic spline:"
na.approx is simple interpolation, and not in the example at all.
===================================
in the next paragraph:
"To get around this instability, we could get some data points from before January 1, 1999, then interpolate using na.spline, or we could simply choose a different interpolation method."
the function which performs spline is "na.spline"
===================================
however, i did a quick check, in zoo document, i can't find na.spline function??
