You do not tell us what you are trying to do but I think there is
something wrong in the logic of your thinking as on the one hand you are
selecting just precisely those elements of data$Rain which are NA and
then testing whether any of them equals 60.

Dear All,
I am getting this error and don't know why it comes. can you please help ?
Error in if (data$Rain[i_NA] == 60) { :
missing value where TRUE/FALSE needed
The loop is :
indicNAs <- which(data$Rain %in% NA)
ind_nonleap = c() # NAs due to non leap years
ind_nonrecord = c() # NAs due to non recording values
for (i_NA in indicNAs ){
if(data$Rain[i_NA] == 60){
ind_nonleap <- append(ind_nonleap,i_NA)
}
else {
ind_nonrecord<-append(ind_nonrecord,i_NA)
}
#cat(ind_nonrecord)
#cat( ind_nonleap)
}
ind_nonleap
