Max() function; want it to return the name of the data not the number

[Jamiet9850]

Hi, I'm not sure how best to describe this but basically I'm trying to classify results of football games as H - Home win, D - Draw and A - Away Win via the probabilities of them winning. So for an individual game, i, I have the code:

results[i] = max(H,D,A)

Where H,D and A are all probabilities between 0 and 1. How do I get the Max function to return, for example, H as opposed to its numeric value (if H is the largest number)?

I do not know the type of the object results, but you can use which.max. If you have a vector like x <- c("H", "D", "A") (may be column names of results as well), you can use this:

results[i] = x[which.max(c(H, D, A))]

Hope this helps.

@Jamiet9850, sorry, I made a bad mistake. Hopefully, I fixed it correctly. Please check the edited code. If it fails again, can you please provide a reprex? Otherwise, I cannot test my code.

@Yarnabrina

results[i] = x[which.max(H, D, A)]

Hi @Yarnabrina, results is just an empty vector that I want to fill with the results of the matches. It's part of a loop if you'd like me to send you that too as the which.max function just returned "Error in which.max(H, D, A) : unused arguments (D, A)".
