Error handling on cr_journals with iSSN / Not found message from the api

[nkorf]

Hi,
First of all great thanks for this amazing package.
I am having a problem with the cr_journals function call with an issn argument. I suspect this has to do with the crossref api not returning any details for a particular issn. If you try to run
the function :
cr_journals("0413-6597")
will return an error message as follows:

Error in x$flags : $ operator is invalid for atomic vectors
In addition: Warning message:
404: Resource not found. 

I suspect it has to do with error handling for a 404 responce, is there a way to circumvent this issue ?

Thanks for the report ! That function and others loop internally so users can pass in many DOIs/ISSNs/etc. - on failure for any one we just throw a warning, but don't stop the function progress - this particular bug we didn't catch appropriately, looking at it now

@nkorf okay, try your eg again after reinstalling devtools::install_github("ropensci/rcrossref")

@sckott Ok it works now. I also used a temporary workaround for the older version to surround the function call with try(). Keep up the great work.

will do, and keep reporting problems
