[R] Error Missing values where true/false needed
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.

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.

[R] Error Missing values where true/false needed
Hi PIKAL, The error seems to be starnge to me because i access the indices of NAs. Indices can't be non-applicable. This is the output of indecs having the NA in my dataset. my dataset is very big that's why I did not provide it.> indicNAs <- which(data$Rain %in% NA) > indicNAs[1] 426 792 1158 1890 2256 2622 3354 3720 4086 4818 5184 5550 6282 6648 7014 7746 8112 [18] 8478 9210 9576 9942 10674 11040 11406 12138 12504 12870 13602 13968 14334 15066 15432 15798 16530 [35] 16896 17262 17994 18360 18726 19458 19824 20190 Regards, Frederic.
