R help - Nov 2010 - How to remove a package.

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)

2: Perhaps you meant ‘Ecdat’ ?

Error: object 'Ecdat' not found

Ecdat can't be found?


Where can I download/install EcDat?  TIA

detach(package:AER) works for me.

you mean "cars" ? This is not part of AER but in a base R
installation.

It is case sensitive, try install.packages("Ecdat") it works for me...

Maybe you should try a little bit more...
