How to create sequence of constant time interval
Dear R-Experts, seek your help. There are two parts I want to deal with. 1) I want to create a time interval of say, 30 minutes starting from "00:00:00" hrs Thus at the end, I want to create sequence: 00:00:00 00:30:00 01:00:00 01:30:00 .. .. How to do so ? Later, I want to change the time-increment value in a variable and changing the value of this variable, I would like to create new sequence with that time increment. How to use "seq()" correctly? 2) I have a date stored in one variable. Say "2009-01-01" How can I combine this date with each time interval in the first part? Will concatenate work? so at the end, I would like to have: 2009-01-01 00:00:00 2009-01-01 00:30:00 2009-01-01 01:00:00 2009-01-01 01:30:00 ... ... Thank you in advance.
