So excited to announce the initial release of {gtExtras}, a #rstats 📦 providing "extras for {gt} tables!

🎉🎉🎉

Includes:
💅 4 full themes
🛠️ 12 utility/formatting functions
📊 5 inline plot types
🎨 3 built in color tools

Thread below of functions:

jthomasmock.github.io/gtExtras/

This package is highlighting capabilities that are all _possible_ with {gt} but have repeated boilerplate or wrap multiple function calls internally.

If you haven't updated {gt} recently, make sure to update as gt v0.3 added full support for tidyeval!

gt.rstudio.com/news/index.htm…

With full support for tidyeval in {gt} and in specific functions in {gtExtras}, you can reference columns and rows just as you would in {dplyr}. You also get all the power of things like:

where(is.numeric)
starts_with("name")

dplyr.tidyverse.org/reference/dply…

Fun fact - in about 20 lines of #rstats code you can scrape a table from @FiveThirtyEight , convert the text to a dataframe, and then recreate the _exact_ table with {gt}/{gtExtras}

Maybe you're more of a fan of ESPN, the NY Times, or The Guardian? There are themes for those too!

Guardian: jthomasmock.github.io/gtExtras/refer…

Maybe you want to have an inline indicator for positive/negatives? We have that too!

With one function call, add in-line "pill" plots indicating wins/losses or positive/negatives! Choose your own palette or use the default.

Ok, so maybe sparklines are more of what you're looking for. Show trends over time and then summary values in the table itself.

jthomasmock.github.io/gtExtras/refer…

Maybe rather than showing trends, you want to show the percentages of each subgroup.

Check out the gt_plt_bar_stack function! It even includes the ability to dynamically change the column labels with colors and specific text.

Beyond just plots, there are other ways to highlight data.

You can quickly highlight specific rows by number or by a logical match.

Want to add some type of unit or symbol to your numbers but still have them align properly? Check out fmt_symbol_first() - has support for specific characters (eg "%") or HTML codes ("%")

jthomasmock.github.io/gtExtras/refer…

You can use the pad_fn() to pad numeric values so they align at the decimal place but don't require all the trailing zeroes!

You can also use gt_text_img() to add an image to the end of your table header. Useful for specifying the group you are working with, or possibly a company logo.

jthomasmock.github.io/gtExtras/refer…

The gt_merge_stack() function allows you to merge two existing columns, and stack them for a more compact but rich display.

jthomasmock.github.io/gtExtras/refer…

Want to know how those inline logos were added? That is gt_image_rows() which allows you to replace inline text representing the image with the actual image!

jthomasmock.github.io/gtExtras/refer…

There are also helpers for applying max/min functions by group, so you can highlight specific values in a grouped gt table.

jthomasmock.github.io/gtExtras/refer…

Lastly, there are color palette functions - the gt_hulk_col_numeric() functions applies the hulk palette ("purple" and "green") as a heatmap within a column or across the table.

jthomasmock.github.io/gtExtras/refer…

Alternatively, the gt_color_rows() function is a wrapper around {paletteer} and gt::data_color() that lets you quickly apply colors to the table. {paletteer} provides dozens of built-in palettes, and the function supports discrete or continuous values.

More features will be built into the package over time, so give it a try and let me know what type of other features you would like to see for HTML tables!
