surv.blackboost breaks when predicting on one data point #309
Description
Description
I tried to debug it, and the actual error occurred in this line
https://github.com/mlr-org/mlr3/blob/435c9d13fae39ef3f3f6cf40cbfae6fc9d19a039/R/worker.R#L175-L182
Possibly connected with mlr3extralearners, mboost.
Reproducible example
library(mlr3proba)
#> Loading required package: mlr3
#> Warning: package 'mlr3' was built under R version 4.2.2
library(mlr3extralearners)
library(survival)
task_veteran <- as_task_surv(veteran, time = "time", event = "status", type = "right")
learner_ranger <- lrn("surv.blackboost")
learner_ranger$train(task_veteran)
learner_ranger$predict_newdata(veteran[1, -c(3, 4)])
#> Error in `colnames<-`(`*tmp*`, value = rownames(newdata)): attempt to set 'colnames' on an object with less than two dimensionsCreated on 2023-01-13 with reprex v2.0.2
