Hi,
I am trying to call R in my perl program but is not working. It does not

I am using the following command to call R from Perl

Any suggestions?

Rolf,
I actually don't believe that this is a SAS vs R issue since I have 3
sources that report the same results. I know that STATA, SAS and the
mima function from R can all be used to give the correct results. The
question is related more to how I can get similar results with lmer.
I have two kind of variables. One kind where the values are continious
and ranges from -1 to 5, and the other is boolean (i.e. true or false).
For example:
V1 V2 V3 V4 V5 V6
0.1 0.4 1 0 -1 3.7
0.4 0.1 2 -1 0 3.7

The problem is in the code.
When you say

(mydata) to label its output.
If you did what you probably intended:
