在 R 中使用“fread”时出现 curl 错误

Question

I was reading a csv file from github using fread of data.table.The code is as follows.

input <- if (file.exists("flights14.csv")) {
  "flights14.csv"
} else {
  "https://raw.githubusercontent.com/Rdatatable/data.table/master/vignettes/flights14.csv"
}

library(data.table)

flights <- fread(input)

An error ocurred:

Error in curl::curl_download(input, tmpFile, mode = "wb", quiet = !showProgress) : 
  Could not resolve host: raw.githubusercontent.com

Is there any way to solve this?

You should try opening the link( https://raw.githubusercontent.com/Rdatatable/data.table/master/vignettes/flights14.csv ) in browser when you are connected to Internet. if it works here it should definitely be loaded to your environment when you are passing it to fread function of datatable.

i tried it and it worked out.
