New page, who dis?

T his is my copy-paste template for new blog posts. I got tired of looking up the same Quarto features every time, so this is essentially just a growing example for me.

YAML frontmatter

Copy this header and adjust:

title: "Your Title Here"
description: "Brief description for SEO and social cards"
date: 2025-01-15
categories: [Statistics, R]
tags: ["brms", "Bayesian"]
draft: false  # set to true to hide
cache: true   # speeds up builds for R-heavy posts

Optional stuff:

• heroImage: Header image path
• lastUpdated: When you edited it

Typography

Drop caps are gorgeous:

<span class="dropcap dropcap--ornate dropcap--serious" data-first-letter="T" aria-hidden="true">T</span> ext starts here...

Math: inline like $\mu = \sum_{i=1}^n x_i$

Citations: (Cinelli, Forney, and Pearl 2020) if you have a references.bib file.

Margin notes:

margin: This appears in the right margin.

Normal notes:

I am not in the morgin but in the middle of the text instead.

R Code

Basic chunk:

library(ggplot2)
library(dplyr)

set.seed(42)
data <- data.frame(
  x = rnorm(100),
  y = rnorm(100) + 0.3 * rnorm(100),
  group = sample(c("A", "B", "C"), 100, replace = TRUE)
)

head(data, 3)

           x          y group
1  1.3709584  0.6006866     B
2 -0.5646982  1.1448842     B
3  0.3631284 -0.6518111     C

Plots

ggplot(data, aes(x = x, y = y, color = group)) +
  geom_point(alpha = 0.7) +
  theme_minimal() +
  labs(title = "Sample Data", x = "X values", y = "Y values")

margin: Chunk options go after #|. Main ones: label, echo, eval, include, warning, error.

Collapsible code

For longer setup that would clutter the post:

<details class="code-collapse">
<summary>Show data processing</summary>
  Code goes here
</details>

processed_data <- data %>%
  filter(!is.na(x), !is.na(y)) %>%
  mutate(
    x_scaled = scale(x)[,1],
    y_scaled = scale(y)[,1],
    distance = sqrt(x_scaled^2 + y_scaled^2)
  ) %>%
  arrange(desc(distance))

head(processed_data, 3)

          x          y group  x_scaled   y_scaled distance
1 -2.656455  3.1449272     B -2.582179  3.3197211 4.205734
2 -2.993090 -0.8387712     C -2.905445 -0.7676472 3.005144
3 -2.440467 -1.4272253     C -2.374769 -1.3714150 2.742317

Standard markdown

Works as expected: bold, italic, code, links, lists, etc.
