Read.csv.ffdf not passing the quote parameter to scan() #55

Closed RonaldPhilipsen closed 5 years ago

RonaldPhilipsen commented 5 years ago

when attempting to read a Csv file that has every value in quotes (eg: "52.3605759") ffbase keeps throwing an error.

the function i'm using is: read.csv.ffdf(file = reviews, quote = "\"")

when i execute this line i get the following error message Error in scan(file = file, what = what, sep = sep, quote = quote, dec = dec, : scan() expected 'a real', got '"51.5137335"'

adding the decimal separator had no effect read.csv.ffdf(file = reviews, quote = "\"", dec = ".")

i expect FF to pass the parameters to scan, and thus read the file.

EDIT: just realised this is an issue with the base FF, can be closed

Thanks for reporting the issue! The function generating the error however is not part of ffbasebut part of ff (which I am not the author of).
