The first approach uses a function to create combinations of district, county and year and only requires six lines of code. Similarly, you can also use facet_grid() to facet by a single categorical variable as well. Excel has three random value functions: RAND (), RANDBETWEEN (), and RANDARRAY (). df which I'm not even going to pretend to understand which expands. Timings are excellent for small to moderate values of m, up to about 10,000, but degrade for larger problems. To recover the subsets, use mypairosubsets=lapply(pairs[p,],function(r) s[subsets[r,]]) where p is the row of the pair you want. Step 2) Adding Extra Row. You can also see if a disk. R. expand() generates all combination of variables found in a dataset. matrix (expand. table and is therefore. Now I want to generate a new variable that assigns a value between 60 and 65 to each of the duplicates. 5. 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.
