I am using random Forest in R and only want to Plot the OOB Error
.
When I do plot(myModel, log = "y")
I get a diagram where each of my class is a line. On the x-axis
are the ntree
while on the x-Axis
there is the Error rate.
When I try plot(myModel$err.rate, log = "y")
I get this:
Why is there no line like the ones above?

The err.rate
is stored in a matrix where the first column is the OOB Error
. Each class gets its own column.
To access the err.rate
do this myModel $err.rate[,1]
, for plotting simply plot(myModel $err.rate[,1])
.
