I need to deciles data containing more than one variables using any one
variable. I am using script below :

id <-c(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20)
tot <-c(1230, 1230, 2345, 3456, 456, 4356, 123, 124, 987, 785, 5646, 345,
2345, 3456, 456, 4356, 123, 124, 987, 785)	
data <- data.frame ( cbind(id , tot))
data$decile<-cut(data$tot,quantile(data$tot,(0:10)/10),include.lowest=TRUE,lable=TRUE)
data$decile

New variable "decile" taking values as below where as I need it should take
values from 1,2..10, Where I am going wrong? 

data$decile
 [1] (987,1.23e+03]      (987,1.23e+03]      (1.23e+03,2.34e+03]
 [4] (2.34e+03,3.46e+03] (301,456]           (3.46e+03,4.36e+03]
 [7] [123,124]           (124,301]           (785,987]          
[10] (456,785]           (4.36e+03,5.65e+03] (301,456]          
[13] (1.23e+03,2.34e+03] (2.34e+03,3.46e+03] (301,456]          
[16] (3.46e+03,4.36e+03] [123,124]           (124,301]          
[19] (785,987]           (456,785]
