New method for identifying spatially variable genes in spatial transcriptomics.

We use spectral graph theory to extract 1D curves related to tissue morphology, creating a more relevant coordinate system. Improves sensitivity.

Question for #rstats educators: Do you use a standard format for exercises?

I have 100s of exercises along with solutions in quarto documents (see image). But they are not formatted in a systematic way. I would like to easily create docs with and w/o solutions and export to LMS.

Data visualization is used in two ways in data analysis:

1) Communicating data insights.
2) Guiding analysis and spotting data issues.

While modern courses and books focus on the first, it's the second - exploratory data analysis - that is more important and harder to teach.
