ggplot example

This blog post will teach you how to create a ggplot using an open-source dataset called ‘penguings’

# install.packages("palmerpenguins")
library(palmerpenguins)
library(ggplot2)

# let's take a brief look at the dataset using head the head function
head(penguins)

## # A tibble: 6 × 8
##   species island bill_length_mm bill_depth_mm flipper_length_… body_mass_g sex

## # … with 1 more variable: year <int>

# now we can create the plot
ggplot(penguins, aes(bill_length_mm, bill_depth_mm, color = species)) + 
  geom_point()
