[R] more about ts and NA's

[Antonio Rodríguez Verdugo]

Hi,

I've seen that handle missing values makes difficult to manage data series
within R. I've look at Shumway's program (ASTSA) and Brockwell & Davis
pogram (ITSM), it seems that both handle NA's values without problem, or
maybe, I'm getting an spurious results? 

My problem is with two variables: rain and river flow: the first has 7 NA
values (is to say, seven months, non contiguous) and the later, 12
contiguous NA values (half of one year and half from the other).

Do you think that the action of erasing those monthly values would be
crucial for the analysis or I just can throw them away (I have monthly data
since 1984 onwards).

Thanks,

Antonio
