I’m having a question, I’d like to take the element a[1]
and compare with b[1,1]
and count as a hit, then the element a[2]
compared to b[2,1]
and so on, always by column. Then I want to compare the a[1]
with b[1,2]
and count as certain, then the item a[2]
with the element b[2,2]
and so on. Later return the column of b which got more hits.
set.seed(1)
a = sample(1:3, 4, replace = T)
b = matrix(sample(1:3, 20, replace = T), ncol = 5, byrow = T)
The desired answer would be column 2 or 5 that if tied I choose one of the columns randomly.
Thanks in advance.
It’s not very clear. You want to compare the vector
a
with each of the matrix columns?– Daniel Falbel
That, element by element.
