read.csv fails in R console in Ubuntu terminal but works in RStudio after R 3.6.3 upgrade to R 4.0.2?

Perhaps read FAQ 7.43? [1]

Hello,

R 4.0.2 on Ubuntu 20.04 LTS, sessionInfo below.

I'm also unable to read the file with Rscript from the Ubuntu terminal
but the error is not the same as the OP's.


The first try was a file test1.R with the following commands.

x<-"https://old.nasdaq.com/screening/companies-by-name.aspx?letter=0&exchange=1&render=download"
read.csv(x, as.is=TRUE, na="n/a")


And run with Rscript

rui at rui:~$ Rscript --vanilla test1.R
Error in file(file, "rt") :
   cannot open the connection to
'https://old.nasdaq.com/screening/companies-by-name.aspx?letter=0&exchange=1&render=download'
Calls: read.csv -> read.table -> file
In addition: Warning message:

   cannot open URL
'https://old.nasdaq.com/screening/companies-by-name.aspx?letter=0&exchange=1&render=download':

The second try was download.file() and then read it.
File test2.R is:

x<-"https://old.nasdaq.com/screening/companies-by-name.aspx?letter=0&exchange=1&render=download"
download.file(x, "companylist.csv")
read.csv("companylist.csv", as.is=TRUE, na="n/a")


But this too failed with error 403 Forbiden.

rui at rui:~$ Rscript --vanilla test2.R
trying URL
'https://old.nasdaq.com/screening/companies-by-name.aspx?letter=0&exchange=1&render=download'
Error in download.file(x, "companylist.csv") :

Hi,

I am trying to download some data using read.csv and it works

perfectly in

RStudio and fails in the R console in the terminal in Ubuntu 18.04

after

upgrading from R 3.6.3 to 4.0.2. Before upgrading this worked in the

R

console in the terminal also without any issues.

Why would that be? How to fix this?

Below please find R code output and sessionInfo().

I also asked this question here

https://stackoverflow.com/questions/62898008/why-read-csv-fails-in-r-console-in-ubuntu-terminal-but-works-in-rstudio-after-r

. Since there was no answer on stackoverflow I sent this question

also to

this list.
