fileurl <- "https://data.baltimorecity.gov/api/views/dz54-2aru/rows.csv?accesstype=download" download.file(fileurl, destfile = "./data/cameras.csv", method="curl")

it gives following error however:

 warning messages:  1: running command 'curl  "https://data.baltimorecity.gov/api/views/dz54-     2aru/rows.csv?accesstype=download"  -o "./data/cameras.csv"' had status    127   2: in download.file(fileurl, destfile = "./data/cameras.csv", method  = "curl") download had nonzero exit status

and if remove method= "curl" 

error in download.file(fileurl, destfile = "./data/cameras.csv") :  unsupported url scheme
