#dplyr — Public Fediverse posts

{duckplyr} is a drop-in replacement for dplyr powered by DuckDB. Keep the familiar dplyr syntax while speeding up work with large datasets: https://duckplyr.tidyverse.org/ #rstats #dplyr #duckdb #datascience

Choosing the wrong join can silently remove observations, duplicate rows, or introduce missing values into your data.

I'm choice 2, using group_nest and map as it retains the original column types and there is no need to rename, although if I put some effort into it I'm sure I could remove the need to enframe and rename. I just don't feel like doing that this morning. #tidyr #purrr #dplyr #imap #map #RandomWalker

Here is a simple script to show what different distribution densities look like. You can easily achieve this using my TidyDensity package. #dplyr #ggplot2 #TidyDensity #R #RStats

It's not going to accept it, but in a good world, it would. #dplyr #RStats

Na #PythonCerrado2025, tivemos ontem um excelente tutorial do Lucas Marcondes Pavelski https://github.com/lucasmpavelski.

Aprendemos sobre #R, #tidyverse, #reticulate, várias ferramentas essenciais como #ggplot2 e #dplyr, vendo na prática como aplicá-las. Foco na ponte #Python <-> R.

Tudo novidade pra mim, vieram várias ideias interessantes de análises e plots.

I recently saw a kind of stacked donut/pie chart that visualized nested count data (e.g. a sample description with two relevant categories, like favorite ice cream and gender) and wondered how I'd do that in #rstats.

So, if you ever want to make a plot like this, here's the #ggplot2 and #dplyr code: https://gist.github.com/Kudusch/577b6f07c686a64a3aace685fd9f3bee

This wouldn't work well with too many categories and pie charts in general aren't optimal, but for this specific kind/shape of data, I think it works well enough.

Last one for today, I just added random_hypergeometric_walk() to the #dev version of my #R #package #RandomWalker this package relies on #dplyr #ggplot2 #stats #purrr #R #RStats #tech #Coding
