Dear Thierry,

So, does it mean that I have to install "nlme" instead of "lme4"? or first "nlme" and after "lme4"???

I also need"lmerTest" and when I installed it, I got the following message:

Installing package into 'C:/Users/Hp/Documents/R/win-library/3.3'
(as 'lib' is unspecified)

package 'lmerTest' successfully unpacked and MD5 sums checked

The downloaded binary packages are in

Loading required package: Matrix
Loading required package: lme4

Attaching package: 'lme4'

The following object is masked from 'package:nlme':

Dear Rui,

nlme is a recommended package, lme4 is (currently) not. You need to install it.

You don't need to install lme4, it comes with base R.
