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.
First you need to explain more clearly what you mean by "place the
result
under Data2". Is this a display concern? Or are you trying to
interleave rows of original data and logged data using a column
organization? Why only Data2? What should go in the rows for Data1 and
Data3? ? What is the goal of this effort?
Does anyone else know?
I have the log2 values, but how do I get then inside the .csv file
under
Data2?
Post some sample code that constructs the data.frames and the code you
used.
I already tried write.table(), buy that wasn't it.
And I am kinda stuck on this now.....
