Primarily used for cases where you load metapackages like tidyverse or tidymodels but only want to return those packages that are actually used. E.g. say you have a library(tidyverse) call but only end-up using functions that are in dplyr -- spot_pkgs() would return "tidyverse" whereas spot_pkgs_used() would return "dplyr".

## Usage

spot_pkgs_used(file_path, as_yaml_tags = FALSE)

## Arguments

file_path

String of path to file of interest.

as_yaml_tags

Logical, default is FALSE. If set to TRUE flattens and puts into a format convenient for pasting in "tags" section of a blogdown post Rmd document.

## Value

Character vector of all packages with functions used in the file.

## Details

Also does not return uninstalled packages or those loaded when R starts up.

Is essentially just calling spot_funs() |> with(unique(pkgs)) in the background. Does not have as many options as spot_pkgs() though.
