I installed the stringr package on my Ubuntu 10.04 machine under R 2.10.1. When I try to use the str_extract() function R stops and gives the following error message:
我在ubuntu10.04机器上安装了stringr包。当我尝试使用str_extract()函数R停止并给出以下错误消息:
Error in recyclable(string, pattern, replacement) : could not find function "vapply"
可回收错误(字符串、图案、替换):找不到函数“vapply”
How can I solve this problem? Is there any specific package that contains this vapply function?
我该如何解决这个问题?是否有包含这个vapply函数的特定包?

vapply is in the base package, so something may be wrong with your installation.
vapply在基本包中，所以您的安装可能有问题。

I'm using Ubuntu and I think the problem is that it's using an older version of R in the repos. I uninstalled R from my machine, then I used this http://www.keittlab.org/node/158 to set up the repos for R. So far this works for me very well.
我在使用Ubuntu，我认为问题是它在repos中使用了一个旧版本的R。我从机器上卸载R，然后使用http://www.keittlab.org/node/158设置R的repos。
