insert: Insert simplices
In simplextree: Provides Tools for Working with General Simplicial Complexes

Description Usage Arguments Details See Also Examples

Inserts simplices into the simplex tree. Individual simplices are specified as vectors, and a set of simplices as a list of vectors.

1	insert(st, simplices)

`st`	a simplex tree.
`simplices`	simplices to insert, either as a vector, a list of vectors, or a column-matrix. See details.

This function allows insertion of arbitrary order simplices. If the simplex already exists in the tree, no insertion is made, and the tree is not modified. simplex is sorted before traversing the trie. Faces of simplex not in the simplex tree are inserted as needed.

If simplices is a vector, it's assumed to be a simplex. If a list, its assumed each element in the list represents a simplex (as vectors). If the simplices to insert are all of the same dimension, you can also optionally use a matrix, where each column is assumed to be a simplex.

find remove

st <- simplex_tree()
st %>% insert(1:3) ## inserts the 2-simplex { 1, 2, 3 }
st %>% insert(list(4:5, 6)) ## inserts a 1-simplex { 4, 5 } and a 0-simplex { 6 }.
st %>% insert(combn(5,3)) ## inserts all the 2-faces of a 4-simplex
