# Introduction

This is a Quarto tutorial based on the official Posit cheatsheet. It features some of the new features in Quarto v. 1.4. 

# Code

Let's insert some inline code in R: `{r} p <- 1 + 1` gives `{r} p`

Here is some `R` code:

```{r}
p <- 1 + 1
print(p)
```

Now, let's import some data and create a graph, after loading the required libraries:

```{r}
#| warning: false # Do not display warnings
library(tidyverse)
```

```{r}
data(iris)
glimpse(iris)
```

We now plot `Petal.Length` vs. `Petal.Width`:

```{r}
#| fig-align: center
#| fig-height: 6
#| fig-width: 8

#| fig-cap: "Petal length vs. petal width in iris species"
ggplot(data = iris, aes(x = Petal.Width, y = Petal.Length)) +
    geom_point() +
    geom_smooth(method = "lm", se = TRUE) +
    ggtitle("Petal length vs. petal width") +
    xlab("Petal width") + ylab("Petal length") +
    theme_bw()
```

::: {.callout-tip title="Consistency" collapse="false"}
Use `dplyr` for data wrangling and `ggplot2` for plotting - keep it consistent

## `Markdown` formatting:

Here is some **bold** text and here is some text in *italics*. We can also <u>text</u> or strikethrough text: ~~hello~~. We can also create some lists. Let's start with a numbered list:

1. First
2. Second
3. Third

Now, let's make the same list, nested:

1. First
   1. Hello
   2. Hi
   3. Ciao
2. Second
3. Third

We can also have unordered lists:

- First
  - Hello
  - Hi
  - Ciao
    - 1
- Second
- Third

We can also insert links to URLs: [my website](https://chlazaris.netlify.app) or links to pictures. Here is a photo of my favorite writer:

We can also insert tables:

|ID|Name|Surname|
|--|----|-------|
|1|James|Dean|
|2|Marlon|Brando|
|3|Montgomery|Cliff|
