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.

ugghhh that's awful! So parse argument isn't really ready
November 3, 2025 at 8:48 PM
Yea no problem :) I like finding things like this!
November 3, 2025 at 8:46 PM
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]))) +

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

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 + ...

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
November 3, 2025 at 8:02 PM
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?

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.
