We use Doxygen to generate the documentation

mf_background() adds background images underneath maps:

library(mapsf)
#> Le chargement a nécessité le package : sf
#> Linking to GEOS 3.7.1, GDAL 3.1.2, PROJ 7.1.0
mtq <- mf_get_mtq()
th <- mf_theme("default", bg = "grey20", fg = "grey80")
mf_init(mtq, theme = th)
mf_background(system.file("img/background.jpg", package = "mapsf"))
mf_map(mtq, lwd = 2, col = NA, border = "grey80",

Currently the C++ code in freud does not ensure that r_min is non-negative (>= 0) in several classes. Values of r_min < 0 should raise an error in the constructor like this:

https://github.com/glotzerlab/freud/blob/eb2a97bac302ed45236f26e0a7e6a0346071c579/cpp/density/RDF.cc#L17-L28

This applies to classes like RDF and CorrelationFunction and other classes that deal with radial dist

This step is often performed by users, but can be confusing. Create a "most common" path for importing in walk networks (perhaps from OSMnx) and support its conversion to peartree.
