R初学者的小问题

quality

请问，有些程辑包用library（）怎么不行啊，比如我输入library(mapdata)

提示是不存在这样的包。我问题是怎样安装这些程辑包呢？麻烦哪位大虾说的具体点，小生刚学R，请教下，谢谢……

回复第1楼的 quality：应该是亲还没有装这个包吧，点“程序包”里的“安装程序包”，装上那个包再library()就好啦~

回复第2楼的 chenyan_ss：谢谢你的回答。可是我在“安装程序包”里面没有找到mapdata这个啊。你帮解答下吗？

> install.package("mapdata")

> library(mapdata)

if you still can't get the package, check R version and its compatibility with the package, or try another mirror site.

回复第4楼的 SnowDrop：>install.package("animation")

package ‘animation’ successfully unpacked and MD5 sums checked

but when I input ">load("animation")",

it happens "Error in readChar(con, 5L, useBytes = TRUE) : cannot open the connection

In addition: Warning message:

In readChar(con, 5L, useBytes = TRUE) :

cannot open compressed file 'animation', probable reason 'No such file or directory'"

回复第5楼的 Say05： maybe missing using load("animation"),if you do this,you threated "animation" as a data file,you can use library(animation) instead
