r - 结合使用R和Google Analytics(分析)

Question

我在此网站http://code.google.com/p/r-google-analytics/上找到了一个很棒的项目r-google-analytics，我想使用它来在R中操纵GA dat。

我运行这段代码:

library(RCurl)

library(XML)

# 1. Create a new Google Analytics API object 
ga <- RGoogleAnalytics()  
# 2. Authorize the object with your Google Analytics Account Credentials
ga$SetCredentials("INSERT_USER_NAME", "INSERT_PASSWORD") 

我收到此错误消息:

Error in postForm("https://www.google.com/accounts/ClientLogin", Email = username,  : 
  SSL certificate problem, verify that the CA cert is OK. Details:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

关于什么可能导致错误的任何想法？

谢谢!

有关详细说明，请参见http://www.omegahat.org/RCurl/FAQ.html，具体说明(取决于您对安全性的偏好):

如果您没有来自适当的签名代理的证书，则可以使用ssl.verifypeer选项禁止对证书进行验证:

x = getURLContent(“https://www.google.com”，ssl.verifypeer = FALSE)
