[datatable-help] fread will not respect stringsAsFactors

[Arunkumar Srinivasan]

Hi Frank,

IIRC it's not implemented yet (irrespective of R or data.table version). I think there's a bug/FR somewhere. Matt hasn't gotten to it yet.

In R 3.1.0 and data.table 1.9.2, I can't get stringsAsFactors to work:  

require(data.table)  
s=fread('http://biostat.mc.vanderbilt.edu/tmp/support2.csv',  
stringsAsFactors=TRUE)  
attributes(s$sex) # NULL; is character
