Sorting in r The tutorial uses six examples to demonstrate how to use the various sorting functions in the R programming language. Example 1: sort vs. order vs. rank (Basic Application) Let’s start by making an example vector in R that we can use in the examples that follow: x <- ...
# R program to sort a vector by index values # Creating a vector x <- c(7, 4, 3, 9, 1.2, -4, -5, -8, 6, NA) # Calling order() function # to sort in decreasing order order(x, decreasing = TRUE) # Calling order() function # to print NA at the end order(x, na.last...
[, 3]) == 0)) # in 2 places, needed 3 cols to break ties: d4s[ rbind(i, i+1), ] ## rearrange matched vectors so that the first is in ascending order x <- c(5:1, 6:8, 12:9) y <- (x - 5)^2 o <- order(x) rbind(x[o], y[o]) ## tests of na.last a <...
By executing the previous R programming code, we have created Table 3, i.e. another data.table sorted in descending order based on the column x2.Example 3: Sort Rows of data.table Based on Multiple ColumnsThe following R programming code illustrates how to order the rows of a data.table...

With special contributions fromMichael Garland, in Programming Massively Parallel Processors (Fourth Edition), 2023 13.1 Background Sorting is one of the earliest applications for computers. A sorting algorithm arranges the elements of a list into a certain order. The order to be enforced by a sort...
