GitHub - hadley/genzplyr: dplyr but make it bussin fr fr no cap dplyr but make it bussin fr fr no cap. Contribute to hadley/genzplyr development by creating an account on GitHub.

Do you teach #rstats? Do your students complain about how lame and old-fashioned dplyr is? Don't worry: I have the solution for you: github.com/hadley/genzp....

genzplyr is dplyr, but bussin fr fr no cap.

Salmon clear last Klamath dams, reaching Williamson and Sprague rivers Just a year after four dams were removed, a group of fall Chinook have migrated nearly 300 miles into the Upper Klamath Basin.

My heart was jubilant while reading this story this morning - more than 100 Chinook salmon have passed the former Klamath River dam sites as well as the fish ladder at Klamath Lake and are naturally spawning in Oregon headwaters for the first time in over a century! ๐ŸŸ๐Ÿงช๐ŸŒŽ

One week to apply for our fully funded PhD position in Norway! This is a really exciting project in collab. with University of Helsinki and Benchmark Genetics.

Samples are ready - you do (read: learn) everything - functional genomics, bioinformatics, genotype-phenotype associations ๐Ÿคฉ

Please RT!

Our research group just published a study in Nature on how fish biodiversity in U.S. rivers and streams has been changing over the past 27 years (1993โ€“2019). The results show sharply diverging trends depending on historic and changing water temperature. ๐Ÿงต rdcu.be/eH0l8

Climate change is reshaping fish communities in the United States | Nature Rising temperatures and the introduction of non-native fishes have been linked to rapid changes in fish communities across the United States. Rising temperatures and the introduction of non-native fishes have been linked to rapid changes in fish communities across the United States.

Climate change is reshaping the fish communities of rivers across the US - my commentary in @nature.com to accompany the new study led by @rumschsl.bsky.social rdcu.be/eHY6B ๐ŸŒ๐Ÿงช

celebrate              package:celebrate               R Documentation

Audio 'announcements' when printing model summaries

Description:

     The only function of this package is to augment the printing of
     model summaries with appropriate sound effects based on whether
     you have achieved the magical p<0.05 level of significance for at
     least one variable (not including the intercept - we have to try
     to be a _little_ bit sensible ...)

Details:

     Sounds are taken from <http://freesounds.org>

     To set an alpha-level different from 0.05, you can specify
     โ€˜options(celebrate.alpha = <value>)โ€™

#lirpaloof Since it's already 2025-04-01 for most of the world ... a slightly updated version of the `celebrate` package: `remotes::install_github("bbolker/bbmisc/celebrate")`. (Description: Celebrate your successes and mourn your failures.) Now supports `htest` objects!

Hi Bluesky, I am happy and optimistic to be here! Anyone know a freshwater fisheries biologist into teaching who might want to come join me in the beautiful Ozark streams of SW Missouri?
Please share/repost.
