Below are two ways I have figured out to do this. 1. e a,b is the same as b,a) shall work, it would be quite slow to compute provided the many combinations I have. NOTE: the implementation is not limited to 0-1 sequences, so it should also work for something like expand. These variables are preserved when you call summarise(), so they behave somewhat similarly to the grouping variables. 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. Another way is to suck the result into igraph and simplify undirected graph (remove duplicate edges). The result would therefore look somewhat like this or should have a content like the following:Combinations of vectors produce a grid of options. stringsAsFactors logical specifying if character vectors are converted to factors. Learn R. 0. Use "minimal" to allow duplicates in the output, or "unique" to de-duplicated by adding numeric suffixes. grid (nrounds = 50, max_depth = 2:3, eta = 0.

Hello Jeffrey, For this specific example, the base R solution is quite elegant. Now, we can use the duplicated () function on the data frame as shown below: # remove duplicated rows based on name df <- df [!duplicated (df [,c ("name")]),] The code above utilizes the “!” operator, in order to indicate that we do not want to keep the duplicated rows based on values found within the name column of the data frame. Fastest way of joining 2 data tables while summarising the data in one of them. The problem is that there are 2 rows of c with behavior=2 (1-12-2020 and 1-16-2020) as you said, but in the final data frame with your method, there are 4 rows of c with behavior=2. expand () generates all combination of variables found in a dataset. e. 3) Video & Further Resources.
