Importing zoo object ("index contains NAs")

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.

Almost certainly there are no NAs in your index (although we can't say for 
sure as Gabor pointed out).

write.zoo(g, file = "gdata.txt", index.name = "date", append = F, 

quote = T, sep = ",")

h <- read.zoo("gdata.txt", sep = ",", format = "Y-%m-%d")

^^^
First problem: This should be %Y.
Second problem: You need header = TRUE.

Thus, I would guess that
   h <- read.zoo("gdata.txt", sep = ",", format = "%Y-%m-%d",
     header = TRUE)
should do what you want.
