getEIA() will now work with version 2 of the EIA API. getCatEIA() has been removed, so if you don't already know the Series ID you want you'll need to find it using an alternative method. For example:
- Go to EIA's Opendata website.
- Go to the "Bulk File Downloads" by scrolling down a bit and looking on the right margin.
- Choose the bulk download for the category that contains the series you want. Foe example if it is a Crude Oil series download the "Petroleum" file.
- After the file downloads unzip it and find the Series ID you want.
Note you only have to do the above once to get the Series ID.
