Hi,

 

Sorry for the question, I know it should be basic knowledge but I'm
struggling for two hours now.

 

How do I select only the first entry of each list member and ignore the
rest?

 

So for 

 

> $"121_at"

> -113691170 

 

> $"1255_g_at"

> 42231151 

 

> $"1316_at"

> 35472685 35472588 

 

> $"1320_at"

> -88003869

 

I only want to select 

 

-113691170, 42231151, 35472685 and -88003869 .?

 

Regards

Benjamin
