find the distinct permutations of columns
Description
find the distinct permutations of columns, particularly in graph applications were describing relationships between unordered nodes, or other applications were the order does not matter
Usage
similar_permutations(edges, to, from)
Arguments
edges |
dataframe, tibble, The data structure to work on |
to |
tidy-eval, character The variable to group by |
from |
The column of values that will collapse into a list. |
Details
The inputs can be anything that casn be input into the paste function.
Value
The inputs pasted together as a character string.
experimant first if it helps
not well supported
on multiple data types
Note
ensure the total values to fold are sufficiently low tp preserve the pretty print aesthetic
Examples
if(!require(dplyr)){library(dplyr)}
edges <- data.frame(
to=sample(c('A','B','C','D'),size = 50,replace=TRUE),
from=sample(c('A','B','C','D','E','F'),size = 50,replace=TRUE))
dplyr::count(edges,to,from)
ordered = similar_permutations(edges,to,from)
dplyr::count(ordered, to ,from)
