formattable | Formattable Data Structures | Development Tools library

I'm trying to use the color_tile on column 'a' and I'm trying to find out how to either ignore the sign, or use the style from column 'c' (the absolute values of a, hiding c after with c=FALSE).

I've seen examples where it uses column 'c' but it uses the actual values inside if statements rather than the style, or the numbers with no manual input. So what I want is for -5 to have the darkest green, and 1 to be without color.

What I have is

I have a dataframe

I am trying to add a black border to a formattable object.

Here is my example table:

Given a dataframe as follows:

I had a data table that worked in shiny using the formatting examples here

The code seems to have stopped working, and instead of a table that is formatted with positive numbers green, negative numbers red, and zero as black, I get a blank output.

For a reproducible example, I used mtcars as a simple shiny example with minimal other code "overhead".

The end goal is to format a table so that the numbers in the table show up colored according to the above.

Appreciate the help!

i am new to R and trying to understand Rshiny to build UIs. I am trying to create a UI for my python app that transcribes mulitple wav files. There are two parts below, first my python app and the second my shiny app in R which uses reticulate to call my transcribe.py app. For some reason though, i do not receive any output.

My Python app works perfectly and does NOT need code review.However, the Rshiny app does not execute the python app correctly to produce the desired result. The objective is to let the user transcribe the files from the UI and decide if they want to download the csv.

I have a python app for transcribing files called transcribe.py-

When hovering over a country the numbers are shown as say 125.115k - I want to show it as 125,115 I tried using library(formattable) and something along the lines of z = comma(worldmap$Deaths,digits = 1)

My code is below

I am creating the following formattable:

I have set the gradient on Var1 so that it gets increasingly red the higher the value is. I was wondering if it would be possible to change it so that it gets increasingly green the higher the value is. I love everything about it as it is, I just want the gradient to go from black to green rather than black to red. I have tried tweaking the numbers in the background-color command, but cannot seem to get it right. Is it possible to fix this? Is there a guide on numeric color gradients that perhaps I'm missing?

I am making the following formattable. Since my data includes multiple groups (not included in the sample data), I will be subsetting my full data frame multiple times to create a table for each factor group in the Group column. I was wondering how I could add a title to the top of the table, so that I can see which subset the table is referring to. For these tables, I would like the title to simply be the value in the value in the Group column. So for the table below, the title would just be "1".
