R is not working for me. What should I do?

Here are a few things you can do to troubleshoot:

1. Check that you've installed the R package and set your API key correctly.
Please ensure that you've installed the R package and set your API key exactly as per the instructions here

If you already have a Quandl account, you can find your API key by logging in at www.quandl.com and going to your Account Settings.

If you do not have an account yet, you may sign up for one here. It is free to create an account and no credit card is required. As soon as you create your account, you'll be able to find your API key by logging in at www.quandl.com and going to your Account Settings


2. Check that you have permission to access the data feed you're trying to access.  
If you are a trying to download data from a premium data feed, you must first subscribe to the feed and complete payment. If you are not subscribed to a premium data feed, you would only be able to download the sample data for that feed. 


3. Check that you are using the correct R command for the format of the data feed you're trying to access.
Data on Quandl comes in two formats: time-series and tables. You can learn more about these formats here.

For time-series data, you must use the Quandl command. See documentation here

For tables, you must use the Quandl.datatable command. See documentation here


4. Check that you are not exceeding usage limits: 

User Type Speed Limit Volume Limit Concurrent Limit
Anonymous Users 20 calls / 10 minutes 50 calls / day 1 call
Logged-In Free Users 2,000 calls / 10 minutes 50,000 calls / day 1 call + 1 additional call in the queue
Premium Subscribers 5,000 calls / 10 minutes 720,000 calls / day No limit
More information on usage limits can be found here

We recommend slowing down and spacing your commands apart to avoid exceeding these limits.  


5. Check if firewalls may be preventing you from downloading data.
See information on Firewall Errors here


6. If you get an error code after making a call in R, check the table below which explains what each error code means and what solution we recommend.
