I want to read in a pretty large csv file from S3 including entries like Hawaii 21"" pizza. However, I noticed that if I use fread (which I do prefer as it's faster), entries include two double quotes changes into Hawaii 21"""" pizza. This kind of issue does not occur if I use read.csv.
I noticed the warning message recommends to add quote="" in order to avoid the issue. But how can I insert it in s3_read_using function?
I can use gsub to make extra quotes disappear, but still wondering if there's any direct solution to it.
And below is my read-in code:
table <- s3read_using(FUN=fread, object='mytable.csv', bucket="mybucket/tables")
table <- s3read_using(FUN=read.csv, object='mytable.csv', bucket="mybucket/tables")
Thanks in advance!
