Hi group,

I am trying to right a code to do the following

This is how the test file looks like:

Chr

start

end

sample1

chr2

9896633

9896683

chr2

-0.35

chr2

14421718

14421777

-0.43

-0.35

chr2

16031710

16031769

-0.43

-0.35

chr2

16036178

16036237

-0.43

-0.35

chr2

16048665

16048724

37491676

37491735

0

chr2

37702947

37703009

Now I want to summarize the values like

Sample

Chr

Start

End

Values

Probes

chr2

9896633

14404502

chr2

37491676

37703009

Here the start for the first line would be the least value until values are
similiar (4) then the end would be highest value. The values is the unique
value among the common values.

Can I get some ideas or suggestions to perform this because I am new to hard
core program in R?

waiting for your suggestions,

Thanks,

Viritha
