I would like to use POSIX classes to store dates and extract components of
dates. Following the example in Spector (Data Manipulation in R), I
create a date
mydate = as. POSIXlt('2005-4-19 7:01:00')
I then successfully extract the day with the command
mydate$day
[1] 19
But when I try to
Month counts from 0 in POSIXlt objects, so that April is month 3 in your
example, January being month 0.
Year counts from 1900 in POSIXlt objects, so that 2005 should return as 105
in your example.
All of the other fields in POSIXlt should return values that you might
expect them to a priori.
