Hi everybody,
I have a 4*4 matrix WD of wind data of the following form:
> WD
$date
[1] "07.07.2010" "07.07.2010" "07.07.2010" "07.07.2010"
$time
[1] "00:00:00" "00:10:00" "00:20:00" "00:30:00"
$CH1Avg
[1] 3.02 3.04 2.94 2.71
I would like to transform the date and time strings in usable numbers for
plotting :
- Transform "07.07.2010" in 07*24 + 07*31*24 for example
- Transform the string of type "12:15:20" in a number equals to
12+15/60+20/3600
I would hence need a function able to look for defined patterns in a list, like
aa:bb:cc and evaluate aa+bb/60+cc/3600.
Anyone has a idea?
Thanks a lot!
Cheers
Olivier Coupiac
