[R] Repeat the first day data through all the day. Zoo

[skan]

# duplicated / na.locf   doesn't work
it says Error in fix.by(by.x, x) : 'by' must specify valid column(s)

if I use ifelse instead of ifelse.zoo it works but it gives me a non zoo
vector.
Myabe is because my zoo version is older.

cheers
