尝试键入以下命令安装所有与拨浪鼓相关的包:
install.packages(rattle, dependencies = c("Depends","Suggests"))
得到了这个
Installing package into ‘C:/Users/Hooman/Documents/R/win-library/3.1’
(as ‘lib’ is unspecified)
Error in as.character(x) :
cannot coerce type 'closure' to vector of type 'character'
我已经在该文件夹中安装了两个单独的包,没有任何问题.
