For the oblique random survival forest model, if there is only one independent variable in the data except for the time and event. The error will happen.

Thanks! Would you be comfortable providing a reprex for this error? I will check it out a little more carefully and see if it's feasible to work in a fix.

For oblique random forests, you don't gain anything from including fewer than 2 predictor variables. Oblique splitting with 1 variable is the same thing as axis based splitting.

PR #56 should fix the error you received. Please don't hesitate to let me know if there are still issues after you download the development version of aorsf
