90 % prediction intervals on out-of-bag data

[oziashub]

Hi. I have carried out a modelling using the function quantregForest 1.3-7. e.g.
qrfozone <- quantregForest(xozone,yozone)
Using plot(qrfozone,all=TRUE) one is supposed to get Estimated 90 % prediction intervals for the Ozone dataset (According to Schiesser, 2015). However, you only get the error as a function of the trees. Is there anything I am missing?

I had the same issue. I couldn't run varImpPlot.qrf function either. It would be great if someone could help us with the problem.
