Error in if (vector1[i] == vector2[j]) { : missing value where TRUE/FALSE needed

I googled for possible solutions, but I did not find a good explanation for this...

vector1 <- sample(1:100,10)

vector2 <- sample(1:100,10)

for (j in vector2) { if (vector1[i] == vector2[j]) { show(list(i,j)) } } }

}

Regards, David
