HI,
Try this:
Date1- seq(as.Date(2012-09-10,format=%Y-%m-%d),length.out=20,by=day)
set.seed(25)
value- sample(c(1:5,NA),20,replace=TRUE)
library(xts)
x1- xts(value,Date1)
colSums(is.na(x1))
#[1] 3
which(is.na(x1))
#[1] 4 6 13
set.seed(38)
value2- sample(c(5:8,NA),20,replace=TRUE)
x2- xts(cbind(value,value2),Date1)
colSums(is.na(x2))
# value value2
# 3 2
sapply(x2,function(y) which(is.na(y)))
#$value
#[1] 4 6 13
#$value2
#[1] 10 17
A.K.
