Getting Started with R
R is open-source and widely used in academia, research, and data science. To begin:
- Install R from https://cran.r-project.org/
- Use RStudio for an enhanced coding experience 📚
- Load datasets with
read.csv()
orread.table()
Basic Statistical Operations
R excels at performing calculations like mean, median, and standard deviation.
mean()
computes the average of a datasetmedian()
finds the middle valuesd()
calculates the standard deviation
Example:
data <- c(1, 2, 3, 4, 5)
mean(data) # Output: 3
Data Visualization
Visualizing data is crucial for insights. Use packages like ggplot2 📈
- Create histograms with
ggplot() + geom_histogram()
- Generate scatter plots using
geom_point()
- Customize themes with
theme()
Advanced Analysis Techniques
Explore regression, hypothesis testing, and machine learning in R:
- Linear regression:
lm(y ~ x, data)
- ANOVA:
aov()
- Clustering:
kmeans()
