That said, I have two issues to ask for help with:
1) how to ignore cert errors with a fromJSON call
And
2) why the json data from the example link doesn't convert to a data frame. As seen in the following example
library("rjson")
result <- fromJSON(file = "https://www.semantic-mediawiki.org/w/api.php?action=ask&query=[[Category:City]]|?Capital%20of|?Has%20area&format=json")
json_data_frame <- as.data.frame(result)
print(json_data_frame)
which results in:
library("rjson")
Warning message:
package ?rjson? was built under R version 3.4.4
Error in (function (..., row.names = NULL, check.rows = FALSE, check.names = TRUE, :
arguments imply differing number of rows: 0, 1
print(json_data_frame)
Error in print(json_data_frame) : object 'json_data_frame' not found

Right. I'm trying to access a server within my organization which has a cert error that I cannot fix.
The example link I provided was to a site on the web that does not have the cert error.
