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

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.
