citation network

Hi,

I am trying to extract a citation network using patentsview.

Fortunatly there is an example that shows how to make it https://docs.ropensci.org/patentsview/articles/articles/citation-networks.html

But unfurtunatly this example generates an error message for me. 

First it writes

"The _eq operator is a safer alternative to using field:value pairs or value arrays in your query"

And then

"Error in UseMethod("as.request") : 

  no applicable method for 'as.request' applied to an object of class "character"

Calls: search_pv ... one_request -> <Anonymous> -> request_build -> as.request

Execution halted"

 

Could you help?

Hi Maksym, I just made…

Hi Maksym, I just made changes to the patentsview R package to address the issue that you mentioned. Follow the instructions for installing the development version of the package (https://github.com/ropensci/patentsview#installation) and then retry your code. I re-ran the citation network example and it seems to be working now.
