Introducing evoFE: Evolutionary Feature Engineering in R for XGBoost and LightGBM Hey everyone, I’m excited to share a new package I've been working on: evoFE (Evolutionary Feature Engineering).…

There are times when I want to use tidyverse code and/or ggplot2 within a loop or function, and I'm never sure the best way to refer to variables. I have an example that seems to work well, but I'm wondering if this is the "best" way?…

Hi! I'm new to R and I'm trying to plot mutation subtypes with the age variable for a melanoma dataset. The code runs perfectly fine but I don't understand why the the geom_col() function keeps plotting weird numbers for age?…

qol is a package which can be used as its own ecosystem concerning descriptive evaluations, data wrangling, tabulation and much more. It offers over a hundret high level functions which make the coding life easier.…

Hi, what would you say are the most common or best ways to model confidence levels, estimates for things like theories or scenarios, for market analysis? submitted by /u/mrsockpicks [link] [comments]

this is kinda a dumb question but if the statement is: "the average salary is less than 500. test this claim", what's the null hypothesis and the alternative hypothesis? submitted by /u/Far-Bad-1441 [link] [comments]

I have a collection of samples (n ~ 20) that I have measured 2 isotopic values of and I want to calculate the likely % contribution of 4 source endmembers for each sample (eg sample 1 is 25% source 1, 12% source 2, 40% source 3, 23% source 4 +/- what…

I'm bringing my substack back to life to talk about AI and data science. I have conflicted feelings about both AI and writing about AI but I want to try and work through them in the open.…

Hello everyone, I’m looking for some advice/validation regarding the web infrastructure for our research lab. We are building two things using R-based frameworks: A static lab website built with Quarto. Several dynamic web apps built with Shiny.…

In biology you often count things: cells of type A out of total cells of type B, mutant flies out of total flies, etc. The most common move in papers is to compute a ratio per animal and run a t-test on the ratios.…

I'm a PhD student and am using the phyloseq and microeco packages in R to analyse microbiome data in R. I have 72 different samples spread over four different conditions and three timepoints.…

I've trained an XGB model using caret (specifically XGBdart). The results are given as a dataframe with 432 rows and I'm not sure how to interpret them. Which values should I use for statistics such as RMSE, R squared and so on?…

Hello everyone, hope you’re all doing well. Has anyone here worked with conformal prediction before? For those who have, have you actually used it in production or in your day to day work?…

Looking through threads and papers, underdispersed count data keeps coming up as a real problem with almost no good fix. For unbounded counts CMP is honestly pretty cool, it goes both directions, glmmTMB exposes it as compois, life is fine.…

R/Medicine showed how much practical innovation is happening at the intersection of R, health data, reproducible analysis, and AI. What's next?…

This year, LatinR will take place in Medellín, Colombia, on November 11–13, 2026. We will meet at the Universidad Antioquia and Parque Explora to learn everything about R.…

This is a very early stage package, but you can do fun things with it: mypaint_device("tmp.png", bg = "grey") plot.new() plot.window(c(-6, 6), c(-6, 6)) set_brush("tanda/acrylic-05-paint") idx <- 0 cols <- rep(c("red4", "blue4"), 3) step <- seq(0, 5, len…
