Go to [CRAN](https://cran.r-project.org/bin/macosx/) and download the latest R pkg. 2. Open the .pkg file and follow prompts. ### Linux Follow distro-specific instructions from [CRAN Linux page](https://cran.r-project.org/bin/linux/). ## Install RStudio (Free) 1. Go to [Posit RStudio Desktop](https://posit.co/download/rstudio-desktop/). 2. Download for your OS (requires R 3.6+ installed). 3. Run installer. ## Verify Open RStudio, run in console: ```r print("Hello, R!") install.packages("tidyverse") ``` No errors = success.

How do I learn r fundamentals?

# R Basics: Syntax and Data Structures Use RStudio console or new script (File > New File > R Script). ## Key Concepts - **Assignment**: `x <- 1:10` (vector 1 to 10) - **Data Types**: Numeric `5.2`, Character `'hello'`, Logical `TRUE` - **Vectors**: `c(1,2,3)`, `seq(1,10)`, subset `x[1]` - **Help**: `?mean`, `help(lm)` ## Practice ```r # Vectors x <- c(10.4, 5.6, 3.1) y <- x + 1 mean(x) # Data frames df <- data.frame(x = 1:3, y = c('a','b','c')) head(df) ``` Read [An Introduction to R](https://cran.r-project.org/doc/manuals/r-release/R-intro.html) Ch 1-3.

How do I master data manipulation?

# Tidyverse for Data Wrangling Load: `library(tidyverse)` ## Key Packages - `readr`: `read_csv('file.csv')` - `dplyr`: filter, select, mutate, arrange, summarize ## Practice ```r library(tidyverse) # Sample data starwars |> select(name, height) |> filter(height > 180) |> mutate(tall = height > 190) ``` Follow [R for Data Science Ch 5-10](https://r4ds.hadley.nz/data-transform.html).

How do I create visualizations?

# ggplot2 for Plots `library(ggplot2)` ## Basics ```r ggplot(mpg, aes(x = displ, y = hwy)) + geom_point() + geom_smooth() ``` Layers: data, aes(), geoms. Practice facets, scales. See [R4DS Visualization](https://r4ds.hadley.nz/visualize.html).

How do I complete a data project?

# Analyze Real Data 1. Download dataset e.g. [mtcars built-in]. 2. Load: `data(mtcars)` 3. Explore: `summary(mtcars)` 4. Wrangle: filter high mpg cars. 5. Visualize: plot mpg vs wt. 6. Model: `lm(mpg ~ wt, mtcars)` 7. Report in R Markdown (File > New > R Markdown). Share on GitHub. Use [Hands-On Programming with R](https://rstudio-education.github.io/hopr/).

Run installer.

Verify

Open RStudio, run in console:

print("Hello, R!")
install.packages("tidyverse")

No errors = success.

Why this step matters:

-Provides a complete setup for coding and data work
-Enables interactive exploration vital for statistical analysis

30-60 minutes

CRAN R installer, RStudio Desktop, Web browser

Definition of Done

•RStudio launches without errors
•Can execute `print('Hello R!')`
•`library(tidyverse)` loads successfully
