I have a data file, 'precip_projected.csv,' that starts like this:
Headworks Portland Water,2370575.38427211,199337.634652112,228,2005-01-01,0.59

There are a bunch of NAs in the data file.
The command to read it produces an error:
rainfall <- read.csv('../data/precipitation/precip_projected.csv', header = T, sep = ',', as.is = T)
Error in `$<-.data.frame`(`*tmp*`, date, value = numeric(0)) :
replacement has 0 rows, data has 113569
Is the error generated by finding a date that looks like the number zero
or by a prcp value of zero?
BTW, I get the same error if I specify stringsAsFactors = F.
