R
R is the dominant language for statistical computing, data analysis, and academic research. With tidyverse, ggplot2, and R Markdown, it's the go-to tool for statisticians and data scientists.
1R & Tidyverse
library(tidyverse)# Tidyverse pipeline mtcars %>% filter(cyl == 6, mpg > 18) %>% select(mpg, hp, wt) %>% mutate(power_weight = hp / wt) %>% arrange(desc(power_weight)) %>% head(5)
# Group and summarize mtcars %>% group_by(cyl) %>% summarize(n = n(), avg_mpg = mean(mpg), avg_hp = mean(hp))
# ggplot2 ggplot(mpg, aes(x = displ, y = hwy, color = class)) + geom_point(alpha = 0.7, size = 2) + geom_smooth(method = "loess") + facet_wrap(~year) + labs(title = "Engine Displacement vs Highway MPG") + theme_minimal()
# Statistical tests t.test(mpg ~ am, data = mtcars) # two-sample t-test cor.test(mtcars$mpg, mtcars$wt) # correlation model <- lm(mpg ~ wt + hp + cyl, data = mtcars) # linear regression summary(model) ```
