在R中卸载RJSONIO

Question

如何卸载RJSONIO包形式R..我尝试过的

> remove.packages("RJSONIO")
Removing package from ‘/Users/akshit/Library/R/3.2/library’
(as ‘lib’ is unspecified)
Error in remove.packages : there is no package called ‘RJSONIO’

但是如果我检查包的路径，我会得到这个

> path.package("RJSONIO")
[1] "/Users/XXXXX/Library/R/3.2/library/RJSONIO"

请尝试detach(package:RJSONIO).这对我很管用。请看下面的试验和错误：

> library(RJSONIO)
> path.package("RJSONIO")
[1] "/home/XXXX/R/x86_64-pc-linux-gnu-library/3.2/RJSONIO"
> remove.packages("RJSONIO")
