[R] How to remove a package.

[Stephen Liu]

Hi folks,

library(AER)
data()

I found the datasets of AER package.

But I couldn't remove AER with:

either
detach("package:AER")

or
detach("package:AER", unload = TRUE)

data()
still found "car" there.

What will be the correct way to remove it?  TIA


Besides:-

I couldn't find EcDat

> library(EcDat)
Error in library(EcDat) : there is no package called 'EcDat'

> library(Ecdat)
> data()
It is the Data sets in package ‘datasets’

> install.packages("EcDat")
Installing package(s) into ‘C:\Users\satimis\Documents/R/win-library/2.12’
(as ‘lib’ is unspecified)
--- Please select a CRAN mirror for use in this session ---
Warning messages:
1: In getDependencies(pkgs, dependencies, available, lib) :
  package ‘EcDat’ is not available
2: Perhaps you meant ‘Ecdat’ ? 

> Ecdat
Error: object 'Ecdat' not found

Ecdat can't be found?


Where can I download/install EcDat?  TIA
