So, here is a `head' of my dataset. Note the `,,' in the 2nd last column.

The documentation says that ",," should be read as "". But instead the
function throws an error (one I can not understand). See here:
R> library(data.table)
data.table 1.8.7 For help type: help("data.table")
R> tt <- fread("sample.csv", verbose=TRUE)
Detected eol as \n only (no \r afterwards), the UNIX and Mac standard.
Starting format detection on line 30 (the last non blank line in the first 30)
Detected sep as ',' and 13 columns
Type codes: 3300320200002
Found first row with 13 fields occuring on line 1 (either column names
or first row of data)
Error in fread("sample.csv", verbose = TRUE) : Unexpected character (
02-F) ending field 12 of line 1
Using na.strings="" does not work either. But I guess that should not
have made a difference anyway?
Then I opened the file in GVim and converted all `,,' to `,NA,' and
re-read the file. This time it works.
R> tt <- fread("sample-with-NA.csv", verbose=TRUE)

The first data row has some non character fields. Treating as a data

I've attached a 100 row sample.csv and a sample-with-NA.csv here for
you to replicate the issue.
Maybe, it is just that I am missing something. Can you explain?
Thanks a lot!
