Hello,
I get the following error when I use the ROSE class balancing method but
when I use other methods like SMOTE, up, down, I do not get any error
message.
Something is wrong; all the ROC metric values are missing:
ROC Sens Spec
Min. : NA Min. : NA Min. : NA
1st Qu.: NA 1st Qu.: NA 1st Qu.: NA
Median : NA Median : NA Median : NA
Mean :NaN Mean :NaN Mean :NaN
3rd Qu.: NA 3rd Qu.: NA 3rd Qu.: NA
Max. : NA Max. : NA Max. : NA
library(DMwR)
d=readARFF("bughunter.arff")
After installing that package and loading pkg:DMwR I get:
Error in readARFF("bughunter.arff") : could not find function "readARFF"
Since you also posted in HTML, I suggest you read the Posting Guide,
restart and R session and post a reproducible example that loads all
needed packages and data.
