This thread is so great! 🤩 To avoid annoying resizing, figured I'd mention an alternative to {ggview}: {showtext} can resize all text to a specific dpi Text is the part that I find I have to fiddle with most when saving #ggplot2 plots, so this usually works for me 😀 #rstats #dataviz

library(showtext)
showtext_opts(dpi = 300)
ggsave(
plot = my_plot,
file = "file_name.png",
width = 6,
height = 4,
dpi = 300
)

Sometimes, data visualization is about using charts to illustrate a key point or conclusion gleaned from analyzing the data. But what if you’re not sure what the conclusion is? Presenting examples from news reporting on the topics of elections, polling and economics, I will talk about how I have grappled with uncertainty and how to communicate it to the public.

You learn to evaluate if what you don’t like is 5% of the job (even if it can feel like 50%), or whether it truly is 50%. I used to think in 2 year windows and took actions to have many open doors. But also to challenge myself and be ready to say at any interview

I think that’s something natural as you learn that no job is perfect. Mine has given me the flexibility to do other things: like be involved in training Mexicans in my field at my undergrad alma mater #LCG-UNAM & @cdsbmexico.bsky.social, or teaching at my PhD alma mater @jhubiostat.bsky.social.

Integration with existing rodent and human single-cell datasets linked these changes to specific neuronal, glial and vascular cell types. In the amygdala, upregulated genes overlapped with schizophrenia risk genes, while downregulated genes were enriched for substance use disorder risk genes.

The left and middle heatmaps link amygdala differentially expressed gene groups to enriched cell types in mouse and human single-cell datasets. The right heatmap compares habenula and amygdala gene groups with genes associated with disorders in large human genetic studies, known as genome-wide association studies (GWAS). Upregulated amygdala genes overlapped with schizophrenia-associated genes, while downregulated genes overlapped with substance-use-disorder-associated genes.

Bulk RNA-seq found 453 differentially expressed genes in the habenula and 3,041 in the amygdala. Upregulated genes: synaptic transmission and ion conductance in the habenula; metabolic and vesicular functions in the amygdala. Downregulated genes: extracellular matrix functions in both regions.

The upper heatmap shows log-fold changes for genes uniquely or jointly differentially expressed in the habenula and amygdala, separated into upregulated and downregulated groups. The lower matrix links these gene groups to enriched Gene Ontology terms in biological-process, cellular-component, and molecular-function categories. Shared downregulated genes are prominently associated with extracellular-matrix and glial functions.
