[R] Breakdown of Vector

[Rajasekaramya]

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
