# Generating Maximal Partial Room Squares in R

Two different greedy procedures for building maximal partial Room squares in R inspired by Meszka and Rosa (2021) using functions from the [wallis](https://mhenderson.r-universe.dev/wallis) R package.

Tested on R4.4.0 with renv 1.0.7, targets 1.7.1 and wallis 0.0.0.9006.

To create the plots below, first install `renv` and install package dependencies:

```

install.packages("renv")

renv::restore()

```

Now run the `targets` pipeline:

```

targets::tar_make()

```
