[R] strsplit with dataframes

[Henrik Andersson]

Hello fellow R people,

I can not figure out a pretty way to use strplit with vectors

Imagine that I got the following data from someone with ID's 
representing several factors

ID 		data
A1-B1-t1	0
A1-B1-t2	1
A1-B2-t1	5
A1-B2-t2	10
A1-B10-t1	0
A1-B10-t2	1
A1-B20-t1	5
A1-B20-t2	10

...

I would like to turn this dataframe to

station substation time data
A1 	B1 	t1	0
A1 	B1 	t2	1
A1 	B2 	t1	5
A1 	B2 	t2	10
A1 	B10 	t1	0
A1 	B10 	t2	1
A1 	B20 	t1	5
A1 	B20 	t2	10
...

This must surely be done easily, but there are not an example like this 
in ?strsplit

Cheers,
