No need to use a for loop. Try something like this

dim(EXAM1) <- c(20,7420/20)
test.breakdown.list <- as.list(data.frame(EXAM1))

Subject: [R] Breakdown of Vector

Hi,

I have a vector of Size 7420. I wanna break down in such a way that every 20 elements of it should be as elements of an list.

Ex
EXAM1
ABC, SDF,
LMN,ERF,EGC,EFG,WER,FRE,QWE,ERT,DGW,QWE,YUR,ERT,GHJ,FHH,....7420 what i want is
Breakdown.list
[[1]]

ABC,SDF,.....20
[[2]]

21.....40
[[3]]

41....50

i thought of using a for loop but i am wondering how to incerment test.breakdown.list<-list()
for( i =0;i<=length(EXAM1);i+20)
{
test.breakdown.list<-Exam1[c(i:i+20)]
print (paste(i))
}

Ias this how we do...please correct me if am wrong.

Regards
Ramya
