加载library(arulesViz)不成功

huwensheng

哪位高手能帮我解决下列问题：
加载arulesViz出现错误，不知道为什么
Error in gzfile(file, "rb") : cannot open the connection
In addition: Warning messages:
1: In read.dcf(file.path(p, "DESCRIPTION"), c("Package", "Version")) :
  cannot open compressed file 'C:/Program Files/R/R-3.1.2/library/arules/DESCRIPTION', probable reason 'No such file or directory'
2: In gzfile(file, "rb") :
  cannot open compressed file '', probable reason 'No such file or directory'

过儿

Error in library(fGarch) : there is no package called ‘fGarch’
写命令library(fGarch)时出现这个提示，可是我在install package时把五个包全导入了啊，该怎么搞？各位大神，菜鸟求救！靠这个期末考试啊！
