Hi! I am facing a problem in understanding the R-Code Suppose I have a dataset named- transact with its values like following: customer_ID shopping_pt record_type 10000000 1 0 10000000 2 0 10000000 3 0 10000000 4 0 10000000 5 0 10000000 6 0 10000000 7 0 10000000 8 0 10000000 9 1 10000005 1 0 10000005 2 0 10000005 3 0 10000005 4 0 10000005 5 0 10000005 6 1 10000007 1 0 10000007 2 0 10000007 3 0 10000007 4 0 How does the following code work and the results of sub and id- id<-transact$record_type==1sub<-train[c(id[2:length(id)],FALSE),]id<-c(id[3:length(id)],FALSE,FALSE) sub2<-train[id,] Thanks in advance!

Hi! Thanks for pointing out the mistake. I am resubmitting my question as follows: Hi!I am facing a problem in understanding the R-CodeSuppose I have a transactional dataset named- "transact" with its values like following:customer_ID <-c(10000000,10000000,10000000,10000000,10000000,10000000,10000000,10000000,10000000,10000005,10000005,10000005,10000005,10000005,10000005,10000007,10000007,10000007,10000007,10000007,10000007,10000007,10000007,10000013,10000013)shopping_pt <- c(1,2,2,3,4,5,6,7,8,9,1,2,3,4,5,6,1,2,3,4,5,6,7,8,1,2)record_type <- c(0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,1,0,0,0,0,0,0,0,1,0,0)transact <- data.frame(customer_ID, shopping_pt, record_type) How does the following code work id<-transact$record_type==1sub<-transact[c(id[2:length(id)],FALSE),]id<-c(id[3:length(id)],FALSE,FALSE) sub2<-transact[id,]Thanks in advance!> Date: Mon, 24 Aug 2015 15:25:09 +0200 > Subject: Re: [R] Understand Rcode- subset > From: thierry.onkelinx at inbo.be > To: butt_its_me at hotmail.com > CC: r-help at r-project.org > > Posting in HTML mangles up your code, making it hard to read.

Just to second Thierry's point, your HTML post is basically unreadable. Please repost as plain text.
