Now, let's create our own df and see what we can get away with.

I’ve read this page so many times. It sounds like a “.” prefix is recommended when using “…”. So does that mean if there are no “…” then the “.” prefix should NOT be used? Or is there ever a case for using them outside of the dot dot dot context?
Dot prefix
What’s the pattern?

When using ... to create a data structure, or when passing ... to a user-supplied function, add a . prefix to all named arguments. This reduces (but does not eliminate) the chances of matching an argument at the wrong level. Additionally, you should always provide some mechanism that allows you to escape and use that name if needed.

You can see the Dust Bowl
Two maps showing vegetation cover for 
the south-central region on the United States in 1890 (left) and 1930 (right). A circle spanning the Oklahoma panhandle and southwest corner of Kansas, where the dust bowl was most severe, call attention to the color (vegetation) change between 1930 (green) and 1930 (yellow).

You can peep Neil the seal from a safe distance on social media. Or (if you also want to take a fun ride) in the show Deadloch.
A color drawing showing a Neil the seal as a large, brown, content pile in the very center between a toppled caution cone and bent bollard. In the far background (at a safe distance) there are four admirers. 

Handwritten text beneath the drawing reads: “Neil is just a lonely teen who wants other huge teen seals to punch on with. Sadly he has to fight bollards and phone boxes and block roads while squishing traffic cones and fences instead.”

“There is so much we don’t know that we don’t even know how much we don’t know.”
A cell from a comic strip that shows seven adorable cartoon whales sleeping upright on a blue watery background. The text reads: 
“Mammals bigger than buses that swim around singing songs — they know many things we will never understand. As for me I only recently found out sperm whales sleep upright in groups. There is so much we don’t know that we don’t even know how much we don’t know.”

It’s #DataViz about color x emotion! Radar plots get some hate (that’s a red, btw). IMO here they get the message across about the relationship between color and a suite of emotion words. www.not-ship.com/pastel-walls...
Set of 10 radar plots. Each plot corresponds to one color, positions around the circle are emotion words, with positive words on the right and negative on the left. The larger the value the more likely the color is associated with the emotion. Black and gray are mostly negative. Blue, green, purple, orange, yellow, pink, and white are positive. Red is mixed with spikes for  love (positive) and hate (negative) Table of 23 emotion words (vertical) sorted from negative to positive, with 12 columns for color (horizontal) sorted from negative (left) to positive (right). A square filled with the corresponding color indicates an association.

#DangermondPreserve is a treasure. I went to help #PointConceptionInstitute scientists site wireless cameras for coastal monitoring. A required part of the job to check and install cameras was literally walking on the beach. 🤩

It does! One detail I liked was the different font used to label categories. A subtle way to give context and link back to the code in the text.

Full figure:
Fraction of estimated coefficients that are significantly different from 0 (given by the size of the colored dots), for different analysis methods (columns) and variable combinations (rows). We show three different sampling intervals (x-axis), where 1 means the smallest time interval (highest temporal resolution or shortest sampling interval) and 100 the lowest, and different degrees and combinations of autocorrelation in the landscape (y-axis). Note, we expect a positive coefficient for elevation (+2) and a negative coefficient (−2) for habitat feature

Raising the bar for Figure 1 like:
Schematic of the implemented analytical methods and simulation study of scenario 1. (A) For each of the replicated landscape settings with different spatial autocorrelation and their combinations, we (B) simulated 20 repetitions of nearly-continuous animal movement tracks influenced by these variables and subsampled the tracks to three different sampling intervals. (C) The tracks of different intervals were analyzed with three method variants (iSSA, RSA, and wRSA).

Different species but look at this Risso’s calf seen with a pod of bottlenose dolphins. So notable that they wrote a paper about it: onlinelibrary.wiley.com/doi/full/10....

This is great! I’m curious about the plot shapes. A scatterplot default is often a circle, so it seems using + was a choice. Any particular reason? I’ve considered using a + because it can be big without totally obscuring what’s behind it, but always bailed & used a circle

A time series for #TidyTuesday showing annual trends in body condition for female and male tortoises Code: github.com/morethangray... #dataviz | #ggplot2 | #r4ds | #rstats
Title: Female tortoises were healthier in places with fewer males

Subtitle: Average body condition of female and male Hermann's tortoises for three locations at Lake Prespa, North Macedonia: Beach (teal), Konjsko (yellow), and Plateau (brown) locations (Summer records only; no 2013 data). A higher score indicates a healthier animal. Circle size shows how many individuals were measured per timepoint. Notably, Plateau males consistently had the most records. 
 
Figure: Two horizontal line plots showing average body condition (y-axis) by year (x-axis), each with three lines corresponding to Beach (teal), Konjsko (yellow), and Plateau (brown) locations. The annual record counts is depicted as a circle overlaid on each line.  Female body condition (upper plot) values for Konjsko are consistently higher than those for Beach and Plateau, demonstrated by the yellow line that is above and distinct from the teal and brown lines. Male body condition values for Konjsko lack this trend, demonstrated by the overlap between the lines for the three locations. The record count for males at Plateau are very large across all time points.

A small red dog with long legs, wearing an olive green vest, is standing in front of a wooden fence with horizontal slats. The dog is standing in profile and facing right, with the front right paw raised in a point. In the foreground are long bunch grasses that are taller than the dog partially obscure it. In the background through the fence is a sidewalk wet from recent rain.

Treatment = adjective (warm vs cool) Scale = noun (enclosure) You need multiple nouns to study an adjective.
Text from a scientific article that says: “Using grammar to identify scales of replication

How can we avoid misidentifying the scale at which to replicate? <highlighted in blue>A good rule of thumb is to use the grammar of one's description of the study as the clue for how to replicate. <end of highlight> For any experiment, we usually use an adjective to describe the factor of interest (temperature, latitude and predation) that precedes a noun (population, species, genotype and individual). In these instances, the adjective identifies the treatment, and the noun identifies the scale at which the treatment was applied, and hence the scale that should be replicated. For example, if you create three warm enclosures and three cool enclosures for an experiment on the effects of temperature on herbivory, then ‘warm’ and ‘cool’ are the adjectives, and ‘enclosure’ is the scale at which the treatment is applied and, therefore, the scale that must be replicated.”

For this card alone I would build a red, white, and green deck.
A Magic The Gathering card called Titanic Ultimatum showing a painting of 2 deliriously happy chiweenie dogs (one tan, one black with tan points) running toward the viewer with eyes glazed and tongues lolling. The card reads: “Sorcery. Until end of turn, creatures you control get +5/+5 and gain first strike, trample, and lifelink. ‘As the ritual dictates, to awaken destruction incarnate you need only serve the kibble.’”. The summoning costs 2 red, 3 green, and 2 white mana. Yes, white mana. Probably because these are dogs.
