Unable to access bucket storage files from R Studio

I have installed R-studio on my Google cloud platform compute instance. By default working directory on R-studio is:

/home/rstudio

Then I mounted a cloud storage bucket on my compute instance. Mounted image path is:

/mnt/gcs-bucket

But when I try to read from files located in this directory on r studio using:

r<-read.csv("/mnt/gcs-bucket/trainS.csv")

I get following error

Error in file(file, "rt") : cannot open the connection
In addition: Warning message:
In file(file, "rt") :
  cannot open file '/mnt/gcs-bucket/trainS.csv': Permission denied

How can I give permissions on files so that they are accessible from R-Studio. I have already tried:

chmod 777 /mnt/gcs-bucket/trainS.csv

But I still get the same error.

Reading file on R works just fine. In R-Studio I an unable change my working directory:

setwd("/mnt/gcs-bucket")
Error in setwd("/mnt/gcs-bucket") : cannot change working directory

Not sure about how to fix the issue with your approach, but here are 2 different approaches to access files from google cloud storage to your R-studio either in GCE or locally that I find pretty easy:

  1. (not secure, but quite convenient) Enable the "share public" in google cloud storage interface,

Enable the "share public"

then access the file from that public link:

read.csv("https://storage.googleapis.com/your-bucket-name/testfile.csv")

If it's a large file, fread() from data.table will be much quicker to load and it gives you an indication of the loading progress(speed, eta):

library(data.table)
fread("https://storage.googleapis.com/your-bucket-name/testfile.csv")
  1. Or you can use the googleCloudStorageR package to download/upload files from R-studio to GCS.
