[R] median for time data

[Jannis]

Hi,


try to convert this to the R time format "POSIXct" or "POSIXlt" via 
strptime(). Then you can simply substract them. I am not sure whether a 
median can be calculated though (should be possible as POSIXct stores 
the value as seconds since 1970....)

Best
Jannis
