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?

#### Best Answer

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])`

.
