Hi R-friends
I don“t know why the "min()" function below return the min value as factor.
When i force the aicc.min using a as.numeric() function, it return a factor
index (1,2,..) and not min value as I want. By the way, I included a
sessionInfo() at the end of this e-mail.
In fact I had the same problem (values as factor) on other part of my script
and I noticed that it occour when I use "cbind()". It is real?
Any idea?
Kind regards,
Miltinho
