Unique Combinations Of All Elements From Two Vectors In R 2 Examples Example 1: creating data containing a row for each unique combination example 1 shows how to construct a data frame consisting of all unique combinations of our two example vectors. for this, we can use the expand.grid function, which is already provided by the basic installation of the r programming language:. So basically, i am looking for a unique combination by considering all the elements of one vector (a) juxtaposed with all the elements of the second vector (b). an ideal solution would generalize to more input vectors.
Unique Combinations Of All Elements From Two Vectors In R 2 Examples Method1 : using expand.grid () method expand.grid () in r can be used to generate a data frame where the rows are all possible unique combinations formed on taking elements from the argument vectors. more than 2 argument vectors can also be specified. the columns can be assigned customized names, otherwise, the row names are automatic. The result is a data frame that displays all unique combinations of elements between the two vectors. notice that the results from the cj () function match the results from the crossing () function. Expand() generates all combination of variables found in a dataset. it is paired with nesting() and crossing() helpers. crossing() is a wrapper around expand grid() that de duplicates and sorts its inputs; nesting() is a helper that only finds combinations already present in the data. expand() is often useful in conjunction with joins: use it with right join() to convert implicit missing. From the function documentation: ‘create a vector of element positions of duplicates in the output of expand.grid on 2 identical vectors’. feel free to inspect the code behind the function, but it is simply a case of codifying the sequence of duplicates into a formula.
