Dear list,
I have an irregular time series saved and exported as a zoo object. What is the
trick to force zoo to ignore the missing dates when reading it back in? Thanks.
> str(g)
‘zoo’ series from 1948-11-02 to 2012-11-06
Data: num [1:14881, 1:8] 1 0 0 0 0 0 0 0 0 0 ...
- attr(*, "dimnames")=List of 2
..$ : NULL
..$ : chr [1:8] "session" "midterm" "day.of.wk" "elapsed" ...
Index: Class 'Date' num [1:14881] -7730 -7303 -7302 -7301 -7300 ...
> write.zoo(g, file = "gdata.txt", index.name = "date", append = F, quote = T,
> sep = ",")
> h <- read.zoo("gdata.txt", sep = ",", format = "Y-%m-%d")
Error in read.zoo("gdata.txt", sep = ",", format = "Y-%m-%d") :
index contains NAs
