counting the occurrence of NA's in multiple vectors in r

Hi guys this is my first post, i need help summing the number of NA's in a few vectors

for example.. 

c1<-c(1,2,NA,3,4)
c2<-c(NA,1,2,3,4) 
c3<-c(NA,1,2,3,4)

how would i get a result that only sums the number of NA's in the vector? 

the.result.i.want<-c(2,0,1,0,0)

Your question isn't well-phrased, but it looks like you want the result of colSums used with rbind and is.na:

> colSums(is.na(rbind(c1, c2, c3)))
[1] 2 0 1 0 0
