I have two binary dataframes `c(0,1)`, and I didn't find any method which calculates the Jaccard similarity coefficient between both dataframes. I have seen methods that do this calculation between the columns of a single data frame.  

Lets say `DF1`

```
DF1 <- data.frame(a=c(0,0,1,0),
                  b=c(1,0,1,0),
                  c=c(1,1,1,1)) 

```

and `DF2`:

```
DF2 <- data.frame(a=c(0,0,0,0),
                  b=c(1,0,1,0),
                  c=c(1,0,1,1)) 

```

What I am looking is a single Jaccard similarity coefficient between the two data frame (not column by column)

Could you help me with this ?
