I'm doing:
> alyL32007z <- zoo(alyL32007,alyL32007$time)
> range(time(alyL32007z))
[1] "2007-01-01 00:00:00 UTC" "2007-12-31 23:30:00 UTC"
But then, while the original variable is:
> summary(alyL32007$NEE_st)
Min. 1st Qu. Median Mean 3rd Qu. Max. NA's
-15.340 -1.615 -0.054 -0.814 0.750 8.965 11124
the variable within the zoo object is different:
> summary(alyL32007z$NEE_st)
Index alyL32007z$NEE_st
Min. :2007-01-01 00:00:00 0.335: 7
1st Qu.:2007-04-02 05:52:30 0.582: 7
Median :2007-07-02 11:45:00 0.611: 7
Mean :2007-07-02 11:45:00 0.063: 6
3rd Qu.:2007-10-01 17:37:30 0.069: 6
Max. :2007-12-31 23:30:00 (Other): 6363
NA's :11124
and I get an error at plotting:
> plot(alyL32007z$NEE_st)
Error in plot.window(...) : invalid 'ylim' value
Any help appreciated,
Thanks
Agus
