small typo in previous: should be
quote=""
(I left behind a single quote by mistake)

Hi Rich,
It's not obvious what would be causing that error from read.csv. But here's
what I would probably try:
Add quote='"" to your arguments. The default is to use surround text
strings with double quotes, but your file doesn't.
Copy the first few rows into another file and try it. If it succeeds, that
would suggest something later on in the file is causing the problem.
The argument sep=',' is redundant for read.csv. In other words, it sets
sep for you. I'd try switching to the more general read.table.
Are the NAs in the file indicated by NA between a pair of commas? Or do you
have successive commas with nothing between them for NA? Not sure what
difference it will make, but it might affect what args you pass to read.table.
Are you absolutely sure there are never any commas in the name?
-Don

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.
TIA,
Rich
