[datatable-help] Odd problem using fread to read in a csv file: no data, just headers

[Farrel Buchinsky]

Any idea why I am getting a data.table with headers only and zero data? How
can I get around the problem.

fread("http://www.cdc.gov/growthcharts/data/zscore/statage.csv", verbose=T)
fails
read.csv("http://www.cdc.gov/growthcharts/data/zscore/statage.csv") succeeds

> statagecdc <- fread("
http://www.cdc.gov/growthcharts/data/zscore/statage.csv", verbose=T)
trying URL 'http://www.cdc.gov/growthcharts/data/zscore/statage.csv'
Content type 'application/octet-stream' length 66087 bytes (64 Kb)
opened URL
downloaded 64 Kb

Input contains no \n. Taking this to be a filename to open
File opened, filesize is  6.2E-05B
File is opened and mapped ok
Detected eol as \r only (no \n afterwards). An old Mac 9 standard,
discontinued in 2002 according to Wikipedia.
Using line 1 to detect sep (the last non blank line in the first
'autostart') ... sep=','
Found 14 columns
First row with 14 fields occurs on line 1 (either column names or first row
of data)
All the fields on line 1 are character fields. Treating as the column names.
Byte after header row is eof or eol, 0 data rows present.
Type codes: 00000000000000 (first 5 rows)
Type codes: 00000000000000 (after applying colClasses and integer64)
Type codes: 00000000000000 (after applying drop or select (if supplied)

Thanks a lot.
