Issue when I try do download a large csv file from dropbox using the read.csv2 function

Question

I have an issue when I try to download a large csv file (170 Mo) from dropbox.

Here is an example of my code :

read.csv2("https://www.dropbox.com/s/m2hkvgcf7zmkdym/example.csv?dl=1", 
quote = "", stringsAsFactors = FALSE)

I get the following error message :

"maximum delay of 60 seconds reached"

It seems there is a limit of time to download the file. After this limit is reached, the execution stops. I have no problems to download smaller csv files.

Try the vroom package, which really speeds up the process of loading your data (from 145s to 45s on my computer). See: read.csv is extremely slow in reading csv files with large numbers of columns
