I would like to use blackboost on a training data set, then use the
output to predict a testing dataset, and finally evaluate the errors.
An example of the code I have written is the following:
train <- read.csv ("train.csv")
test <- read.csv ("test.csv")
boost <- blackboost (ogred ~ elev + slope + aspect, data = train)
pred <- predict (boost, newdata = test)
pred yields the following matrix:
[1] 2.697689 3.551352 2.761541 3.271642 2.313459 2.207247 1.591521 3.752257
[9] 2.976793 2.522219 1.988676 2.092666 3.550917 2.134925 2.534842 2.922136
[17] 2.277653 2.922136 2.922136 4.593132 2.922136 3.773274 4.647789 3.773274
[25] 4.647789 2.369810 2.645859 2.344808 1.760087 2.918108 2.714825 2.972284
[33] 3.466973 2.001098 1.706958 1.749830 1.960923 1.960923 2.451370 2.835255
[41] 2.443585 3.392883 3.164294 2.615430
I would like to know how to use this output to classify data the
testing dataset. Any advice is much appreciated.
Thank you,
Kirsten
