note: whole function is below- I am sure I am doing something silly.
when I use it like USGS(input=precipitation) it is choking on the
precip.1 - subset(DF, precipitation!=NA)
b - ddply(precip.1$precipitation, .(precip.1$gauge_name), cumsum)
DF.precip - precip.1
DF.precip$precipitation -
I don't think you can do this
precipitation!=NA)
have a look at ?is.na

I suspect what you want here is
ddply(precip.1, gauge_name, transform, precipitation = cumsum(precipitation))
