How do I install r and rstudio?

# Install R and RStudio ## Download and Install R 1. Go to [CRAN](https://cran.r-project.org/mirrors.html) and select a mirror. 2. Choose your OS: - **Windows**: Download the base installer (e.g., R-4.5.2 for Windows). - **Mac**: Download the .pkg file (e.g., R-4.5.2-arm64.pkg). - **Linux**: Follow distro-specific instructions. 3. Run the installer with default settings. ## Install RStudio 1. Visit [Posit RStudio Desktop](https://posit.co/download/rstudio-desktop/). 2. Download the free Desktop version for your OS (requires R 3.6.0+). 3. Install and launch RStudio. Open RStudio console and run `2 + 2` to verify.

How do I learn core syntax and data structures?

# R Basics Read [An Introduction to R](https://cran.r-project.org/doc/manuals/r-release/R-intro.html) sections 1-3. **Key Concepts:** - **Vectors**: `x <- c(1, 2, 3)` or `x <- 1:10` - **Arithmetic**: `y <- x * 2` - **Functions**: `mean(x)`, `summary(x)` - **Help**: `?mean` or `help(mean)` - **Lists/Matrices**: `m <- matrix(1:6, nrow=2)` Practice in RStudio console. Save workspace with `save.image()` and load with `load()`.

How do I handle data frames and import data?

# Data Frames & Input From R Intro sections 6-7: - **Data Frames**: `df <- data.frame(x=1:3, y=c('a','b','c'))` - **Read Data**: `df <- read.csv('file.csv')` or `read.table()` - **View**: `head(df)`, `str(df)`, `summary(df)` - **Builtin**: `data(mtcars); View(mtcars)` Install packages: `install.packages('datasets')` Practice attaching: `attach(mtcars)`.

How do I manipulate data and visualize?

# Tidyverse Basics Install: `install.packages('tidyverse')`; `library(tidyverse)` **dplyr**: - `filter()`, `select()`, `mutate()`, `arrange()`, `summarise()` Ex: `mtcars %>% filter(mpg > 20) %>% select(cyl, mpg)` **ggplot2**: `ggplot(mtcars, aes(mpg, wt)) + geom_point()` Follow [R for Data Science](https://r4ds.hadley.nz/) chapters 3-5.

How do I build a mini-project and explore?

# Apply Skills in a Project 1. Download [mtcars or iris] dataset. 2. Explore: summary stats, wrangle outliers. 3. Visualize trends (e.g., ggplot scatter). 4. Simple model: `lm(mpg ~ wt, data=mtcars)`; `summary()`. 5. Export: `write.csv(df, 'output.csv')`. Read Hands-On Programming with R for examples. Install swirl: `install.packages('swirl'); library(swirl); swirl()`.

Why this step matters:

-Sets up a professional coding environment optimized for R
-Enables interactive coding and visualization essential for data work

30-60 minutes

Web browser, CRAN R installer, RStudio Desktop installer

Definition of Done

•R and RStudio installed successfully
•RStudio opens and runs `R.version` showing 4.5.2 or later
•Console executes `2 + 2` returning 4

Common Mistakes to Avoid

❌ Installing RStudio before R

→Install R first; RStudio is an IDE that requires R

❌ Selecting wrong OS/architecture

→Match your system: 64-bit recommended for modern hardware
