How to read a data file in RStudio from Azure data lake (storage account)

SHAIKH, Alif Abdul 56

I am able to upload and download data file in RStudio from Azure data lake (storage account) using AzureAuth and AzureStor packages with service principal Authentication.

I want to read a data file in RStudio from Azure data lake (storage account).

@SHAIKH, Alif Abdul Thanks for the question. Are you using the azure databricks R studio and Azure ML R studio?

you can use the fread() function from the data.table package to read the data file. This function is often faster than read.csv() for reading large files.

# Load the required packages  
library(data.table)  
library(AzureAuth)  
library(AzureStor)  
  
# Set up your Azure authentication credentials  
azure_auth(tenant = "YOUR_TENANT_ID",  
           client_id = "YOUR_CLIENT_ID",  
           client_secret = "YOUR_CLIENT_SECRET")  
  
# Set up your Azure storage account information  
azure_store_account("YOUR_STORAGE_ACCOUNT_NAME", "YOUR_STORAGE_ACCOUNT_KEY")  
  
# Set up the file path to your data file in the Azure data lake  
file_path <- "abfss://YOUR_CONTAINER_NAME@YOUR_STORAGE_ACCOUNT_NAME.dfs.core.windows.net/path/to/your/file.csv"  
  
# Use the fread() function to read the data file  
data <- fread(file_path)

This will read the CSV file at the specified file path in the Azure data lake and store the data in a data table called data. You can then work with the data in R as you would with any other data table.

I am trying to navigate the R command in Azure ML R studio, getting the below error:

Load the required packages

library(data.table)
library(AzureAuth)
library(AzureStor)

Set up your Azure authentication credentials

azure_auth(tenant = "xxxxxxxxxxxxxx",

client_id = "xxxxxxxxxxxxxx",

client_secret = "xxxxxxxxxxxxxx")
Error in azure_auth(tenant = "xxxxxxxxxxxxxx", client_id = "xxxxxxxxxxxxxx", :
could not find function "azure_auth"
