Re: [R] Splitting Data Frame into Two Based on Source Array
data_main[ match(src,data_main$V1), ] and the compliment of src (call it srcc) data_main[ match(srcc,data_main$V1), ] ...this only works so long as there is only one occurrance of each item in V1 in V1. --Adam On Tue, 9 Sep 2008, Gundala Viswanath wrote: Dear all, Suppose I have this data frame: data_main V1 V2 foo13.1 bar 12.0 qux 10.4 cho 20.33 pox 8.21 And I want to split the data into two parts first part are the one contain in the source array: src [1] bar pox and the other one the complement.

Dear Gundala, Try this: # Data set data_main=read.table(textConnection(V1 V2 foo13.1 bar 12.0 qux 10.4 cho 20.33 pox 8.21),header=TRUE) attach(data_main) closeAllConnections() # Criteria src=c('bar','pox') # data_child1 data_main[V1%in%src,] # data_child2_complement data_main[!V1%in%src,] See ?%in% for more information.

Re: [R] Splitting Data Frame into Two Based on Source Array
Try this which gives a list of two data frames: split(data_main, data_main$V1 %in% c(foo, bar)) On Mon, Sep 8, 2008 at 11:17 PM, Gundala Viswanath [EMAIL PROTECTED] wrote: Dear all, Suppose I have this data frame: data_main V1 V2 foo13.1 bar 12.0 qux 10.4 cho 20.33 pox 8.21 And I want to split the data into two parts first part are the one contain in the source array: src [1] bar pox and the other one the complement.
