Retrieve ChemSpider API keySource:
Look for and retrieve ChemSpider API key stored in .Renviron or .Rprofile.
To use the any of the functions in
webchem that access the
ChemSpider database, you'll need to obtain an API key. Register at
https://developer.rsc.org/ for an API key. Please respect the Terms &
You can store your API key as
CHEMSPIDER_KEY = <your key> in
.Renviron or as
options(chemspider_key = <your key>) in .Rprofile.
This will allow you to use ChemSpider without adding your API key in the
beginning of each session, and will also allow you to share your analysis
without sharing your API key. Keeping your API key hidden is good practice.
