How do I get the getURL function to work in R?

Question

I am trying to work with JSON in R Studio and have installed the RJSONIO and Rcurl packages successfully but the getURL function is not working. I keep getting an error saying that the getURL function cannot be found.

  package ‘RCurl’ successfully unpacked and MD5 sums checked
  Warning in install.packages :
  cannot remove prior installation of package ‘RCurl’

 > AccidentURL <- "http://data.maryland.gov/api/views/pdvh-tf2u/rows.json? 
 accessType=DOWNLOAD"
 > apiResult <- getURL(AccidentURL)
 Error in getURL(AccidentURL) : could not find function "getURL"

Any suggestions on how to get this function to work or how to build the function myself would be appreciated.

The Maryland data portal is backed by Socrata so you can use the RSocrata package with it as well. — hrbrmstr, Nov 10 '18 at 17:42

library(httr)
AccidentURL <- "http://data.maryland.gov/api/views/pdvh-tf2u/rows.json?accessType=DOWNLOAD"
apiResult <- GET(AccidentURL)

output
