Re: [R] can not execute two functions - env() and profile()

2010-04-14 Thread pnouvellet 

Hi,
I had the same problem on windows with same R version...
With the package lme4a (from R-forge), I can use the env() function.

However, I am still unable to use the profile function (in the aim of
establishing confidence interval for the std devaition of random effect). 

any help will be greatly appreciated!!

[R] can not execute two functions - env() and profile()

2010-04-12 Thread Mao Jianfeng 
Dear R-helpers

I want to express my respect and thankfulness to all of you.

When I tried to follow a draft book on lme4 authored by Prof. Doug.
Bates (http://lme4.r-forge.r-project.org/book/) to learn how to fit
mixed-effects model, I found I can not execute two functions which
listed in the book chapters.


For example, in the Chapter 1 of that book there are two lines of R
code, which are:

env(fm1ML)$Lambda # page 14

pr1 - profile(fm1ML) # page 16

I got

there is no env function in R and

error: UseMethod(profile) : profile can not find the available
methods for the object mer

I need to know how can I execute these functions properly in my PC.
Thanks for your helps and advice in advance.

Following is my system info.
