R Question

My original table looks like below:

`A B`

1 a,b

2 c,d,e

3 f

I want to get result as below:

`A B`

1 a

1 b

2 c

2 d

2 e

3 f

How can I use R to do this?

Answer Source

We can use `cSplit`

```
library(splitstackshape)
cSplit(df1, "B", ",", "long")
# A B
#1: 1 a
#2: 1 b
#3: 2 c
#4: 2 d
#5: 2 e
#6: 3 f
```
