Hi,


I am making my way down the learning curve of R, and find it a great
language with so many helpful users!

Below is an example of what I'm trying to do, but can't quite figure out the
right path to go down.

 

Here's what I have:

 

Main is a time series of data with columns Cola and Colb

                Cola       Colb

1              1              1

2              1              1

3              1              1

4              -1            1

5              -1            -1

6              -1            -1

7              1              -1

8              -1            -1

9              -1            -1

10           -1            -1

 

What I would like is to subset the data into groups -  rows 1-3 into one
group (Cola and Colb both =1), then row 4 by itself, then rows 5-6, then row
7, then rows 8-10.

Group 1

                Cola       Colb

1              1              1

2              1              1

3              1              1

 

Group 2

                Cola       Colb

1              -1            1

 

Group 3

                Cola       Colb

1              -1            -1

2              -1            -1

 

Thank you for your help!

 

Ian
