By default, it takes a number as double in R. And we have to add L to change it to an integer. But why L? We could have used A,B, C, etc or any other Alphabet?

which.max ties method in R
(4 answers)
Closed 2 years ago.
I have the problem, now you see that:
x<-c(1,2,3,6,4,5,6)
y=(which.max(x))
print(y)
*The result is 4 because it is the position of element 6 (max value). But I want the result returned is 4 and 7.
How can I do that?
Try the below:
which(x==max(x))
[1] 4 7
If you have potential NA values, use
which(x==max(x, na.rm=T))

Basically, I am iterating through some values, some which may be NA. If it is NA, I'd like to set it to 0.
For example
if (myValue.is.na){
myValue=0
}
