Hi guys, I have many rows (>1000) and columns (>30) of "geno" matrix. I use the following loop and condition statement (adapted from someone else code). I always have an error below.  I was wondering if anyone knows what's the problem & how to fix it.  
Thanks,Zhengyu  ########### geno matrix P1  P2  P3  P4 
1  2  2  3 2     
 2  2  2  1 1

for(i in 1:4) {
 cat(i,"")
 if(sum(geno[i,]!=2)>3 && sum(geno[i,]==1)>=1 && sum(geno[i,]==3)>=1){
   tmp = 1
   }
} ########### 1 2 Error in if (sum(geno[i, ] != 2) > 3 && sum(geno[i, ] == 1) >= 1 && sum(geno[i,  : 
  missing value where TRUE/FALSE needed
