这两天装了R 2.11.1版在mac 上，一切都好只是发现当点击data manager时候会爆出如下错误与警告：
Error in help(dt[i], package = pkg[i], htmlhelp = TRUE) :
  unused argument(s) (htmlhelp = TRUE)
In addition: Warning messages:
1: In data(package = .packages(all.available = TRUE)) :
  datasets have been moved from package 'base' to package 'datasets'
2: In data(package = .packages(all.available = TRUE)) :
  datasets have been moved from package 'stats' to package 'datasets'


然后data manager里边什么也没有，可明明有import data进去，况且R本身就有很多data sets，不懂得到底出了什么问题。哪位大大帮我解答一下，谢谢！
