我想使用 download.file() 将数据从 nse-india.com 读取到 R，如下所示。
url = 'http://www.nseindia.com/content/historical/EQUITIES/2014/SEP/cm24SEP2014bhav.csv.zip'
temp = tempfile()
download.file(url, destfile = temp,method = 'wget')
它抛出以下错误：
SYSTEM_WGETRC = c:/progra~1/wget/etc/wgetrc
syswgetrc = C:\PROGRA~2\GnuWin32/etc/wgetrc

无论如何请让我知道解决这个问题。
编辑：或者从 R 中下载文件的任何其他方法也很棒。
您需要设置一个类似浏览器的用户代理字符串，以便网站认为您是浏览器而不是自动抓取/下载机器人：
