R中的download.file（）具有非零退出状态 [英] download.file() in R has non zero exit status

问题描述

我正在尝试在R 3.0.1（Windows 7）中下载一个文件：

I am trying to download a file in R 3.0.1 (Windows 7):

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

我检查了网址和我的互联网连接，他们似乎工作正常。但是，我收到以下消息：

I checked both the url and my internet connection and they seem to be working just fine. However, I get this message:

    Warning message:  
    In download.file(fileUrl, destfile = "./data/cameras.csv", method = "curl") : 
    download had nonzero exit status

在线找不到任何帮助，任何人都知道如何解决这个问题？

Can't find any help online, anybody knows how to fix this?

推荐答案

但我认为主要的问题是您不必要地使用 https 。我认为这样做：

The answer by @dickoa probably works, but I think the major issue is that you are using https unnecessarily. I think this works:

# Note the http instead of https
file<-'http://data.baltimorecity.gov/api/views/dz54-2aru/rows.csv?accessType=DOWNLOAD'
read.csv(file)
