Odd Behavior Out of setdiff(...) - addition of duplicate entries is not identified
...duplicate entries is not caught by the setdiff(...). Is this expected behavior?
If so, is there another method or approach that should be used to identify duplicate row entries between two different data frames?
Thanks in advance for any feedback.
Test1_DF<-data.frame(HouseSize=c(1:100))
Test2_DF<-rbind(Test1_DF, Test1_DF)
setdiff(Test1_DF, Test2_DF)
integer(0)
setdiff(Test2_DF, Test1_DF)
integer(0)
However,
Test3_DF<-data.frame(HouseSize=c(1:25))
setdiff(Test1_DF, Test3_DF)
