ppi {latte}

Compute the primitive partition identities

Description

ppi runs 4ti2's ppi program to compute the primitive partition identities, that is, the Graver basis of 1:N.

Usage

ppi(N, dir = tempdir(), quiet = TRUE, shell = FALSE, ...)

Arguments

N

A postive integer > 2

dir

Directory to place the files in, without an ending /

quiet

If FALSE, messages the 4ti2 output

shell

Messages the shell code used to do the computation

...

Additional arguments to pass to the function

Value

A matrix containing the basis as its columns (for easy addition to tables)

if (has_4ti2()) {

ppi(3)
t(ppi(3)) %*% 1:3
plot_matrix(ppi(3))

graver(t(1:3))
plot_matrix(graver(t(1:3)))

ppi(5, quiet = FALSE, shell = TRUE)
