I have never written my own function, psedocode, in R. Can anyone show me how to write a psedocode if I want to return, say, like mode or class...? Thanks [[alternative HTML version deleted]]

Hi, I have two lists 1) List1- 30,000 rows and 104 columns 2) List2- a list of 14000 selected rownames  from List 1 Now, I want to extract all the 104 columns of List1  matching with the 14000 selected rownames from List2.  Psedocode will be something like this: match rownames(List2) with rownames(List1) extract selected matched 104 coloumns from (List1) strore in-> List3 So the resulting List3 will contain 14,000 rows and 104 coloumns. How do I do it in R ? Regards, P Barah Department of Biology, Norwegian Unive...
