I'm not sure this is really a mac question but since there is a mac issue with downloading that I have solved with package::download I offer this suggestion. Need to know your working or target directory name (or create it with path.expand) since download.file does not do path expansion.


Also note that your url is either malformed or at the very least confusing. Cannot tell if it is https: or http:. Should just be:


fileUrl <-
"http://data.baltimorecity.gov/api/views/dz54-2aru/rows.csv?accessType=DOWNLOAD"

# Then with downloader installed and assuming that a ./data/ subdirectory exists:

library(downloader)
download( fileUrl, destfile=path.expand("./data/cameras.csv")

Note that it would be more typical on a Mac to see "~/" than "./" or to see a setwd("./data") call.

thanks, it helps a lot but I get the following instead of downloading:

100  9443  100  9443    0     0  26789      0 --:--:-- --:--:--
--:--:-- 46517     0      0 --:--:-- --:--:-- --:--:--     0
, also I tried
and the output is:

100  9443  100  9443    0     0   7196      0  0:00:01  0:00:01
--:--:-- 65576      0 --:--:--  0:00:01 --:--:--     0

Hi Valentina:

That's ok...that's how it downloads.

If you do
file.show("cameras.csv")

you will see your file

That's not an error message.

It's actually telling you that you got 9443 bytes. If the first number were 0, then you would be concerned (and you would have seen some sort of error message).

If you saw messed up output like that, you're probably using RStudio, 
which doesn't display download.file output properly.  In other front 
ends this would appear as a progress report.
