Re: [R] Delta in time series

Try this: > library(zoo) > Lines <- "2009-03-09 12:00:00,1 + 2009-03-09 13:30:00,2" > z <- read.zoo(textConnection(Lines), sep = ",", tz = "") > 1/frequency(as.zooreg(z)) [1] 5400 noting that 5400 seconds is 1.5 hours. On Wed, Jun 10, 2009 at 5:04 AM, koj wrote: > > Hi all, > > I have time data

[R] Delta in time series

Hi all, I have time data in the following format: 2009-03-09 12:00:00 2009-03-09 13:30:00 Now I want to compute the delta between the two time points, which results in this example in 1,5 h. I tried this via "ts" and the related functions but so far without sucess. Can anybody help me? Thank y
