Centos 6.3 R安装错误

我是新手centos，所以我尝试安装R。它已安装，但在编写控制台时出现此错误

R

dyn.load（文件，DLLpath=DLLpath，…）中出错：无法加载 共享对象'/usr/lib64/R/library/utils/libs/utils.so'：
/usr/lib64/R/library/utils/libs/utils.so:未定义的符号： libssh2\u代理\u另外断开连接：警告消息：程序包 未找到选项（“defaultPackages”）中的“方法”错误：package “grDevices”没有命名空间。此外，警告消息： 1:在选项（“defaultPackages”）中找不到程序包“utils”。2: 在选项（“defaultPackages”）中找不到程序包“grDevices”错误 ：包“grDevices”没有命名空间。此外：警告 消息：选项（“defaultPackages”）中的程序包“图形”未显示 在dyn.load（文件，DLLpath=DLLpath，…）中发现错误：无法 加载共享对象'/usr/lib64/R/library/methods/libs/methods.so'：
/usr/lib64/R/library/methods/libs/methods.so:未定义的符号： libssh2\u代理\u另外断开连接：警告消息：包“stats” 在选项中（“defaultPackages”）在启动期间未找到-警告 消息：在选项（“defaultPackages”）中找不到包“方法”

这个错误怎么办？我没有任何功能。 比如,

install.packages("test")

错误：找不到函数“install.packages”

谢谢更新libssh2为我解决了这个问题

下面，我分享了我安装R的经验，因为我遇到了一个类似的问题，这是在相当多的胡闹之后通过简单地更新libssh2包解决的

安装了R版本3，一旦启动，它就会抛出关于加载共享对象失败的各种错误，每个错误都以神奇的错误“undefined symbol:libssh2_exit”结束，我试图找出这些对象的错误，并试图使用ldconfig强制加载它们，但我所有的尝试都白费了！这些文件存在，而且看起来无论如何都不会损坏

}

最后，我决定检查libssh2版本，发现我的版本是一个现代版本，一旦我更新了它，那些错误就消失了

你好，Shareef。如果“这不是一个真正的答案”，我不会发布答案。如果你认为它可以解决某人的问题，请随意发布。更新

libssh2

也为我解决了这个问题。我建议你把它放在回答的最上面。
