R All Combinations Of Two Columns at Keira Woolley blog

R All Combinations Of Two Columns. As an example you might want to generate all pairs of elements in a, b, c without (a,a), (b, b), (c,c). It gives back a list of all combinations of two columns. To find all unique combinations of x, y and z, including those not present in the data, supply each variable as. Apply the crossing function to the same vector twice. To find the possible combinations i'd typically use the combn function. In some situations you want to generate all combinations of distinct elements from a given set. A solution is to order var1 and var2 (the ordering is alphabetical) then use unique. I did this with data.table out of convenience, but it. Columns can be atomic vectors or lists. The choose function can show me how many possible combinations. Since thomas's solution does not work (anymore), here is a base r solution. This is easy to achieve with crossing and a filter: To find all unique combinations of x, y and z, including those not present in the data, supply each variable as. Columns can be atomic vectors or lists. These subgroups can be defined by multiple variables.
