You might want to look at the "segmented" package on http://cran.r-project.org and the accompanying paper. Some important questions are: is the point at which the data changes from flat to decreasing known? (I presume not...) Does it correspond to some change in the process being measured? Do you want to estimate it?

Subject: [R] best way to fit a model

Hi,

I have some data that have this behaviour:

|
|*******
|        *
|          * 
|            *
|              *
|----------------

What is the best and simpler way to fit this in R?

Thanks
Ronaldo
