[R] ifelse reformulation

[brunosm]

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?

Regards,

Bruno
