@cjyetman @jdhoffa the PR is unfortunately rather large as it replaces long ish sankey functions.

This is roughly what you should expect:

• Running the analysis works exactly the same way it used to
• The sankey plot png looks more ggplot2-ish (see image in the description of this PR)
• the data set corresponding to the sankey plot has gained an additional column that contains the currency, as I added title and axis descriptions to the plot which required additional information
• the rest: see above

where does output_file_sankey_sector come from in this updated script?

not sure, but I would've guessed that using tools::toTitleCase() would require adding tools to the DESCRIPTION file to avoid a R CMD check warning? (I know tools is included in base R, but I thought R CMD check was picky enough about that 🤷🏻)

[cjyetman]

apparently not though, no notes in the CI checks
