rarity(c(1,2,3, NA), 1) returns NA with an inscrutable warning, should just return 3 (perhaps with warning about NA values) by default.

Looks like for gamma distribution, if Hill-Simpson = richness, fit_SAD throws an error. Should give a more specific error/warning.

Skeleton code from Wickham and Bryan's R Packages book:

You need the suggested package for this function

my_fun <- function(a, b) {
if (!requireNamespace("pkg", quietly = TRUE)) {
stop("Package "pkg" needed for this function to work. Please install it.",
call. = FALSE)
}
}

There's a fallback method if the package isn't available

my_fun <- function(a, b) {
if (requireNamespace("pkg", quietly = TRUE)) {
pkg::f()
} else {
g()
}
}

Since many users will be familiar with the "q" parameterization used in vegan, iNEXT, etc., might be good to have an option (not default) to use "q" instead of "l". Will need good warning messages, implement across all main functions.

Rdpack seems very helpful for package development, but would be nice if everyone building the package didn't have to install it. Is there a way to get the functionality for citations, anything else it is used for, without requiring another dependency?

Right now vignette figures look funny in html rendering (mainly the balance plots) with pkgdown.

Right now, the internal function MeanRarity:::fancy_rep requires integer abundances, and the rarity plot entirely depends on the output for this. Probably needs a separate pathway to construct non-integer abundance version.

rarity(c(10,1),-1e4) returns Inf, should be about 1.1
