Hello everybody,
I have two datasets, observed and predicted.
Since my observed dataset is not in regular intervals, I need to filter my
predicted dataset based on the measurement date of my observed data.
Here, is an example similar to what I have
library(chron);library(zoo)
DATE<- seq(as.Date("2009-01-01"), as.Date("2009-05-01"), by = 1)
mydat<- rnorm(length(DATE), 20,5)
myzoo<- zoo(mydat, order.by = DATE)
DATE2<- seq(as.Date("2009-01-01"), as.Date("2009-01-30"), by = 7)
Now I need to create a new zoo object with index as DATE2 and corresponding
data values.
window(myzoo, DATE2)
See the vignettes for more details.
Best,
Z
Any kind of help will be highly appreciated.
Thanks in advance you very much
