[R] Error Missing values where true/false needed

[Frederic Ntirenganya]

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

Regards,
Frederic.
