Hello:
Thanks in advance for your time ?

I am having a data.frame with one of the columns containing the weeks as follows. How can I do the following in the most efficient way ?

1. Find the minimum date ?
2. Find the maximum date ?
3. How do we sort based on ascending order the date ?

An example as follows.

Week
1-Jan-01 (<----- MIN DATE)
7-Jan-01
14-Jan-01
21-Feb-01 (<----- MAX DATE)

What is a good way to do these most effectively in R ?

Thanks
Shyam
