I would be more than happy to help out - off the bat usethis::use_github_actions() will give you a base to work off of and from there I would imagine {kaltoa} has some more in depth setup due to its reliance on C++, meaning you'll need to edit the yaml.

Travel from the comfort of your own home this #25DaysofFishmas as we explore fishes from all across the US each day in December. Best part? No sleeping on air mattresses in guest rooms!

The road trip kicks off with fishes from the southeastern US on Monday Dec. 1!

Earlier this summer I finished this print version of my map from last year depicting our Great Lakes as islands. Been trying to learn more about lighting techniques in Blender—I think this was a big leap forward from 2024 version!

Today is World Fisheries Day! 🎣

Fishing has been an essential part of human history for thousands of years and continues to support communities around the world. In recent decades, technological advances have expanded the range of fishing vessels and increased their efficiency,

Closing the fisheries will not change the decline. There are many environmental factors here that are largely out of our control that are causing the decline. Tighter envi. Regs, will help, and citizen doing their part. By closing it you end up ruining many people’s livelihood.

Michigan lawmakers seek $500M to stop mussels, save Great Lakes whitefish - Bridge Michigan US Reps. Debbie Dingell and Tim Walberg are planning legislation to boost research to control invasive mussels, following Bridge Michigan reporting about the impending collapse of whitefish.

Michigan lawmakers want to greatly increase funding for invasive mussel control research in the #GreatLakes to $500 million over the next 10 years - as Great Lakes Fishery Commission's Greg McClinchey says in this article: "Mussels are this generation’s sea lamprey" bridgemi.com/michigan-env...

ugghhh that's awful! So parse argument isn't really ready

Yea no problem :) I like finding things like this!

It seems like parse argument is now the the suggested way to handle this at least that's my brief view just skimming it, but the PR they implemented on the issue for now seems to have made this fixed

1) install v4.0.0.9000 from GitHub.

2) need to add paste to make it render properly

devtools::install_github("tidyverse/ggplot2")
library(ggplot2)
ggplot(mtcars, aes(wt, mpg)) +
geom_point(size = 2) +
annotate(geom = 'text',
x = 4,
y = 32.75,
size = 6,
label = expression(paste('Concentration of', ~CO[2]))) +
theme_minimal()

expressions as annotations broken · Issue #6622 · tidyverse/ggplot2 I think this is due to the recent update. It used to work. library(ggplot2) ggplot(mtcars, aes(x = wt, y = mpg)) + geom_point() + annotate("text", x = 3, y = 30, label = latex2exp::TeX("$\\alpha + ...

This closed issue from September may still exist in v4.0.0 but maybe if installing dev version it is fixed.

github.com/tidyverse/gg...

Error in `annotate()`:
! Problem while setting up geom aesthetics.
ℹ Error occurred in the 2nd layer.
Caused by error in `list_sizes()`:
! `x$label` must be a vector, not an expression vector.

this is ggplot2 4.0.0

what version - use ggplot2 not tidyverse

Why wouldn’t it be? There’s two observations at the same y axis level so why couldn’t this also be in that distribution. Maybe I don’t understand your question. I’m also guessing the x axis is age and y axis is something like GSI?

Reach out to Great Lakes scientists please

Some good advice in here but one critical piece I always give is this:

Get a hobby. Preferably a mildly social one. One that has NOTHING TO DO WITH SCIENCE. NOTHING.

You need friends. Not colleagues. FRIENDS. Friends who will love you no matter your research prospects...

The Swedish University of Agricultural Sciences launches large-scale fish tracking – aiming to provide new insights about fish in the Baltic Sea SLU has deployed 80 acoustic receivers along two lines in the Baltic Sea. By listening for signals from tagged fish, the receivers will reveal migration routes and uncover new insights on life beneath...

FINALLY! 🥳

A Baltic Sea Tracking Network is on the way!! Thanks in part to a receiver loan from @oceantracking.bsky.social members of ETN based at SLU & LUKE (Finland) have deployed what we hope is just the beginning 💪

This package has data that can be used instead of nycflights13 to teach joins, and also to look at temporal trends and draw maps. It has to coolest hexsticker vahdatjavad.github.io/ecotourism/ and cute creatures: mantarays, gouldian finches, glow worms and orchids

I haven't used {DeclareDesign} before, but I have been using {marginaleffects} in my simulation-based power analyses for the past year or so, and I recommend you do too.

Opinion: Let’s both celebrate – and worry about – our Great Lakes on World Lake Day Canada’s freshwater benefits us greatly - and we need to return the favour

Obviously, and laughably wrong. Whales do not in fact fly into windmill blades. Entanglement in fishing gear, and getting hit by ships is the main cause of right whale deaths. And the other whale species are doing just fine in the Atlantic.

African Union backs campaign to replace Mercator map that distorts Africa's size Organizers behind the Correct The Map campaign say the Mercator map's shrinking of Africa minimizes the continent's global influence — and is just plain inaccurate.

We’ve been able to successfully tag alewife with v7 and v6 Innovasea tags in Lake Ontario and Huron. We have also have also early detections indicating they survived and have been moving around.

Thank you for clarification, given the four points you bring up I can see its usefulness, especially using with native pipes and type sensitivity.

I get that it’s type safe but overall replace_when() seems redundant to me.

Are these not just a wrapper around case_when()?

This is the way
