Citation networks
Hi.
I am trying to make a citation networks by reference to "https://docs.ropensci.org/patentsview/articles/articles/citation-networks.html".
However, there are some error which example code was run.
Console:
> # Look up which patents the relevant patents cite
> rel_pats_res <- search_pv(
+ query = list(patent_number = rel_pats$patent_number),
+ fields .... [TRUNCATED]
The _eq operator is a safer alternative to using field:value pairs or value arrays in your query
error : 'q' param is missing
Could you help me ?
