Yup, as mentioned here https://github.com/Kotlin/dataframe/issues/558 only Comparable
is supported, Number
is not supported (yet) but can still be called. This should be fixed indeed. I would say Number
should be attempted to be converted toDouble()
if it's not a known type.
If you have a
DataFrame
consisting of a mix ofNumber
types, callingmedian
on it will break.Example:
Will throw:
java.lang.ClassCastException: class java.lang.Long cannot be cast to class java.lang.Integer (java.lang.Long and java.lang.Integer are in module java.base of loader 'bootstrap') at java.base/java.lang.Integer.compareTo(Integer.java:59) at org.jetbrains.kotlinx.dataframe.math.MedianKt.quickSelect(median.kt:43)
