R offers max and min, but I do not see a really fast way to find another value in the order, apart from sorting the whole vector and then picking a value x from this vector.
Is there a faster way to get the second highest value, for example?

We can find the minimum and the maximum of a vector using the min() or the max() function. A function called range() is also available which returns the minimum and maximum in a two element vector.
max() in R The max() is a built-in R function that finds the maximum value of the vector or data frame. It takes the R object as an input and returns the maximum value out of it. To find the maximum value of vector elements, data frame, and columns, use the max() function.
To get the top values in an R data frame, we can use the head function and if we want the values in decreasing order then sort function will be required. Therefore, we need to use the combination of head and sort function to find the top values in decreasing order.
which. max() function in R Language is used to return the location of the first maximum value in the Numeric Vector.
Use the partial argument of sort(). For the second highest value:
n <- length(x) sort(x,partial=n-1)[n-1] Slightly slower alternative, just for the records:
x <- c(12.45,34,4,0,-234,45.6,4) max( x[x!=max(x)] ) min( x[x!=min(x)] ) If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
