Note to self: It's been awhile since I've needed to do back indexing to return a single row of data while using #RStats.

So, here's a Base R and dplyr refresher 👇

I recently enjoyed using the {gganimate} #RStats package for #DataVis animations. So, I explored it further and drafted some notes. What resulted was some example animations using the palmer `penguins` dataset and some B1G QB passing data from {cfbfastR}.

I was pleased with the outcome. Links 👇

Thought about exploring imputation, but opted to forward fill values using the #tidyverse instead.

[13/x] Today's D3.js focus was to add axes to my scatterplot example. Began to better understand group elements. I also learned about arrow function expressions in JavaScript: developer.mozilla.org/en-US/docs/W...

[12/x] More progress learning D3.js. I got a scatterplot started. Today's focus: scales. I really like @ocks.org 's definition: "Scales are functions that map from an input domain to an output range." (via www.amazon.com/Interactive-...)

[10/x] Made some progress today with the #rstats {htmlwidgets} package and D3.js. Today's challenge: transform data from R to JavaScript. {jsonlite} was helpful in creating the array of arrays needed for D3. `console.log()` was indispensable.

[6/x] Today's D3.js focus: better understand how to work with the coordinate system while using {r2d3} #rstats' package. Mozilla's web docs were useful: developer.mozilla.org/en-US/docs/W.... It helped me solve the positioning of the plot's labels, which was related to bar placement. My progress👇.

[5/x] I should have read the docs closer. I'm still wrestling with how to map elements to the SVG's x & y coordinates.

👨‍💻 GitHub Gist link of progress thus far: gist.github.com/collinberke/...

[4/x] Made some progress with D3.js today. It took me a bit to understand how to translate example code when using the #rstats {r2d3} package.

Today I learned about #rstats {dplyr}'s `group_map()` and `group_walk()`. `group_map()` is really useful for iterating a function on groups within a tibble. `group_walk()` is great for splitting and writing a .csv file by group.

Here are a few examples using the palmer penguins data 👇
library(tidyverse) glimpse(penguins) penguins |> group_by(species) |> group_map(~ quantile(.x$body_mass, probs = c(.05, .5, .95), na.rm = TRUE)) # Write a csv file for each island penguins |> group_by(island) |> group_walk(~ write_csv(.x, file = paste0(.y$island, "_penguins.csv")))
