If A. grid for repeated combinations of a vector in groups? Hot Network Questions I feel trapped as a parent. @Henrik, thanks. Each row needs to be surveyed twice but not from the same person. grid function in R provides a quick way to write out every combination of the elements in n vectors. I have a small example like the following: df1 = data. 1. Combinations using expand. mat,5,replace=FALSE) #Mapping the random id to a random pair r. 1, set the names of the list with 'ln' values and apply expand. The result of expand. 4 [1] 2. I can extract or count the duplicates based on the overlapping dates, which might be. Also if duplicates are allowed within a vector you would have to start with: lapply (my_list, unique). As stupid as this sounds, when things get really big, it can mean not only processing your data in smaller amounts but using other techniques than asking expand. ffdf.

The bottom approach uses a combination of paste, expand. grid(). matrix(do. 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. Grid items have an initial size of min-width: auto and min-height: auto. import numpy as np def random_grid (size=4): r = list (range (1, size+1)) baseline = np. In an iterative process I want to make the persons "walk around" in the grid, but I do not want to occur that two persons are in the same cell at the same time. I know, it sounds pretty complicated, but what I basically want is to apply expand. grid() except that combinations with repeated elements are not included. Same as expand. At the same time, I want the MTOW and nr. grid from base R. However, this is causing me issues for both displaying the data and creating relationships. Returns a tibble, not a data frame. Description. expand. Viewed 1k times. So we can substitute r + (n - 1) as n: For our example of 3 scoops of ice cream from 3 tubs, the number of combinations with repetition is: I wrote the function in R: If there are several matrix arguments, they must all have the same number of columns (or rows) and this will be the number of columns (or rows) of the result. For example, in this worksheet, the January column has price information I want to keep. unnest_wider () takes each element of a list. 8 [1] 3. This works. Returns a tibble, not a data frame. Examples Run this code # NOT RUN {# Simple example of expand. grid on the unique elements of each column. Solution: Step 1: Select the data range.

Expand the cell range by dragging your cursor to the last cell and release the button. I need to generate all the combinations of 1:n repeated n times. 11. This differs from the merge function from the base package in that merging is done based on 1 column key only. For sample the default for size is the number of items inferred from the first argument, so that sample (x) generates a random permutation of the elements of x (or 1:x ). anyDuplicated (unlist (my_list)) > 0 should be more efficient. Value expand() generates all combination of variables found in a dataset. merge values from one dataframe onto another without creating duplicates in R. Now, we can apply the slice, rep, and n functions as. Go to the Data menu => Data cleanup => Remove duplicates. Alt+Ctrl+Page Down/ Alt+Ctrl+Page Up.
