Hi 

I am new to R, randomForest and I have read about how to use it in your old
mails. I have also run the predictions examples from CRAN. But I still don't
understand how to use it right. 

 

The thing that I don't understand is how to run the result from the
randomForest on one line (post) with newdata to get a good guess. What I
mean is if I put in a new observation of iris how do I see what flower it
is? And with what probability (proximity) is that guess? 

 

I have taken a random post from iris database and taken the species data
away and tried to use it as new data but I have not succeeded in finding out
what species it is.

 

How do I write that in R?   

 

And how do I get the guess if it is a regression problem?

 

Is it possible to get it with unsupervised learning? One post with new data
resulting in a good guess?

 

Thank you

Rolf
