无法安装动物园包(R)

Question

我正在尝试下载动物园包以使用时间序列:

install.packages("zoo")

但我收到以下消息:

--- Please select a CRAN mirror for use in this session ---  
Warning: unable to access index for repository http://cran.cnr.Berkeley.edu/bin/windows/contrib/2.12 
Warning: unable to access index for repository http://www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/2.12  
Warning messages:  
1: In open.connection(con, "r") :
  unable to connect to 'cran.r-project.org' on port 80.  
2: In getDependencies(pkgs, dependencies, available, lib) :
  package ‘zoo’ is not available  

我尝试了几个不同的镜子,并且我一直得到同样的错误......动物园在大多数镜子中都没有,或者出了什么问题？

请参阅FAQ 2.19.或者,快速搜索"无法连接到'cran.r-project.org’端口80"上rseek.org.
