```
df <- data.frame(
A = c(2,1,2,0,0,1),
B = c(4,5,3,0,1,3),
C = c(1,0,2,0,7,4),
D = c(3,2,1,0,0,0)
)
row.names(df) <- c('one','two','three', 'four', 'five', 'six')
df
A B C D
one 2 4 1 3
two 1 5 0 2
three 2 3 2 1
four 0 0 0 0
five 0 1 7 0
six 1 3 4 0
```

Hi I would like to count the number of elements in each row that are not 0, and store it as a new data frame with one column and the same number of rows as the original. If I did this the solution would look like this:

```
A
one 4
two 3
three 4
four 0
five 2
six 3
```

???? Thanks!!!
