Census data is currently stored temporarily.

 In order to speed up performance, reduce API quota usage, and reduce unnecessary network calls, please set up a persistent cache directory by setting the environment variable CM_CACHE_PATH= '<path to cancensus cache directory>' or  setting options(cancensus.cache_path = '<path to cancensus cache directory>')

 You may add this environment varianble to your .Renviron or add this option, together with your API key, to your .Rprofile.
