I have a dataframe like this:

```
 V1  V2  V3
 a   b  X:12..500(1)
 c   d  Y:34..1000(-1)

```

And I want to split the last column into different columns 

```
V1  V2  V3  V4  V5  V6
a   b   X   12  500  1
c   d   Y   34  1000 -1

```

I have tried to use "str\_split" in package "stringr", but it seems could not recognize ".."

```
 test <-data.frame(str_split_fixed(df$V3,":",2))

```

I believe there is many other ways to do it. Thanks
