I was working with some excel files with a lot of data. 
And by hand it is impossible to handle them. 
So they are now converted to .csv. 

With headers above the columns, like:  
Data1, Data2, Data3 

But now I needed to calculate the log2 value of Data1 and place the result
under Data2. 
I can't find how to do that. 
Does anyone else know? 

I have the log2 values, but how do I get then inside the .csv file under

I already tried write.table(), buy that wasn't it. 
And I am kinda stuck on this now.....
