Hello R users, I have a problem to delete rows in a table which are not duplicated in order of an id number
a short example: x <- data.frame(cbind(id=c(1,2,2,2,3,3,4,5,6,6), value=1:10)) x_new <- x[which(duplicated(x$id)),] > x_new id value 3 2 3 4 2 4 6 3 6 10 6 10 The problem is that my command not only delet the id number which occur only one time. Also the first row with the id number (2,3 and 6 is deleted). Thanks!
