[R] Merging

[Simon Pickett]

Hi,

I'm pretty sure you dont mean "merge" since merge() creates a new big data 
frame from two small ones. It appears that you want to omit some rows.

As I said before, get used to selecting rows like this

data.frame<-data.frame[data.frame$conditional.rows>1000,]

(for example)

Although I dont have a clue what criteria you are using to select the rows 
you want...

Simon.
