[R] looking for setdiff equivalent on dataset
Hi everybody !
little question.
I have 2 dataset
TheLittleOne<-data.frame(cbind(c(2,3),c(2,3)))
TheBigOne<-data.frame(cbind(c(1,1,2),c(1,1,2)))
And I would like to obtain the TheBigOne - TheLittleOne (the row in
TheBigOne not in TheLittleOne
The result should be:
cbind(c(1,1),c(1,1))
Have you any idea?
PS : this function work.. but too slow and too much complex!..
diff2data<-function(data1,data2){
afaire<-setdiff(paste(data1[,1],data1[,2]),paste(data2[,1],data2[,2]))
afaire<-data.frame(t(data.frame(strsplit(afaire," "
if (sum(dim(afaire))
!=0){afaire[,1]<-as.numeric(as.character(afaire[,1]));afaire[,2]<-as.numeric(as.character(afaire[,2]))}
return(afaire)}
