quarto-authoring

Assign a label with a type prefix such as fig- or tbl- to the element, then reference it with @label in the text. For code cells use #| label: fig-plot with #| fig-cap, and for markdown tables wrap them in a div with {#tbl-name}.

Rename .Rmd to .qmd, change output: html_document to format: html, and move chunk options into #| hashpipe lines using dashes instead of dots, such as fig-cap instead of fig.cap. Quarto can also render .Rmd files directly for incremental migration.

Cell-level cache: true only works for R cells with the knitr engine. For Python and Julia via the jupyter engine, install jupyter-cache and set execute: cache: true in the document YAML front matter.

Quarto auto-detects the engine from the first executable cell: {r} selects knitr, {python} selects jupyter, and {julia} selects the julia engine. All hashpipe options and cross-reference syntax are identical, but table rendering and inline code behavior differ between engines.

Cross-references fail when the label lacks the correct type prefix such as fig-, tbl-, sec-, or eq-, or when the reference omits the @ symbol. Quarto uses tbl- for tables, not the bookdown-style tab- prefix.

Create a _quarto.yml file with project type website, define navbar entries, and add a listing page pointing to a posts directory for blogs. Posts use standard YAML front matter with title, date, categories, and an optional preview image.
