YMMV, but I am a faithful of the tidytable package for expressing things in a tidyverse style with data.table under the hood. Perhaps not all that different from the dtplyr suggestion here

Tidy Interface to data.table

A tidy interface to data.table, giving users the speed of data.table while using tidyverse-like syntax.

Hi folks! I know it is the weekend, but I'd like to quickly announance an update to {legendry} version 0.2.0:

teunbrand.github.io/teunbrand_bl...

#rstats #ggplot2

A scatterplot of the gapminder dataset, showing GDP per capita on the x-axis and life expectancy on the y-axis. The points are sized by population, which has a legend with overlapping circles.

A correlation heatmap of the mtcars dataset. Car names on the left are decorated with a dendrogram. The bottom cells also have a dendrogram, whereas the labels are on the top.

Do you want to use different versions of a figure for HTML, PDF for online vs. print, perhaps an animated GIF for the former, but a static image for the latter?

I now dedicate the first 20+ lines of my user facing functions to argument validation.

I cannot emphasize how helpful this is for preventing bugs.

just remembered this scales R package function that quickly makes your large dollar amounts into human friendly units, and it takes care of those changing units from say millions to billions #RStats

scales::label_dollar(scale_cut = cut_short_scale()

reference: scales.r-lib.org/reference/la...

Screenshot of a y-axis of a graph showing that large dollar amounts are shown in human friendly units, like five hundred million dollars and one billion dollars
