Hi, i'm trying to simplify some R code but i got stucked in this: test<-data.frame(cbind(id,x1,x2,x3,x4,x5,x6,x7)) test
> test id x1 x2 x3 x4 x5 x6 x7 1 1 36 26 21 32 31 27 31 2 2 45 21 46 50 22 36 29 3 3 49 47 35 44 33 31 46 4 4 42 32 38 28 39 45 32 5 5 29 42 39 48 25 35 34 6 6 39 31 30 37 46 43 44 7 7 41 40 25 23 42 40 24 8 8 27 29 47 34 26 38 28 9 9 25 35 29 36 43 34 23 10 10 24 44 37 26 27 46 22 11 11 38 50 32 49 37 24 40 12 12 20 34 48 25 30 41 36 13 13 26 46 20 40 29 20 43 14 14 33 37 49 31 47 30 30 15 15 43 39 27 35 48 47 27 count40<-ifelse(test$x1==40|test$x2==40|test$x3==40|test$x4==40|test$x5==40|test$x6==40|test$x7==40,0,1) count40 I'm trying to remake that ifelse. If any variable from x1 to x7 equals to 40 --> 0, else --> 1 I was trying to do something like: count40aux<-ifelse(test[,2:8]==40,0,1) count40aux It doesn't work as i expected... Can anyone help me please?
