Consistent with knitr syntax highlighting, used_here() adds a summary table of R package & function usage to a knitted Quarto or R Markdown document

## Usage

used_here(fil = knitr::current_input())

## Arguments

fil

If the usage summary is required in the document you are currently knitting, then no argument need be specified.

If you want to create a summary by running just the code chunk, then it is necessary to specify the quoted name of the saved file. You should first load and attach the packages used in a fresh R session.

## Value

A printed kable table with the css class "usedthese"

## Details

If the rendered summary includes rows where the package name is multiple packages separated by a comma, this will be due to an unresolved conflict. The recommended approach is to use the 'conflicted' package.

## Examples

# Simple example which mimics a two-line script and creates
# an html table with a CSS class "usedthese"
usedthese::used_here("mean(c(1, 2, 3))\nsum(c(1, 2, 3))")
#> <table class="usedthese table table-striped" style="margin-left: auto; margin-right: auto;">
#>   <tr>
#>    <th style="text-align:left;"> Package </th>
#>    <th style="text-align:left;"> Function </th>
#>   </tr>
