Surprising length() of POSIXlt vector (PR#14073)
Arrays of POSIXlt dates always return a length of 9. This
is correct (they're really lists of vectors of seconds,
hours, and so forth), but other methods disguise them as
flat vectors, giving superficially surprising behaviour:
strings <- paste('2009-1-', 1:31, sep='')
dates <- strptime(strings, format="%Y-%m-%d")
print(dates)
# [1] "2009-01-01" "2009-01-02" "2009-01-03" "2009-01-04" "2009-01-05"
