Presentation of Palmer Penguins Dataset Unsing R Markdown

The Palmer Penguins dataset is comprising various measurements of three different penguin species, namely Adelie, Gentoo, and Chinstrap. The dataset contains 344 observations.

The rigorous study was conducted in the islands of the Palmer Archipelago, Antarctica. These data were collected from 2007 to 2009 by Dr. Kristen Gorman with the Palmer Station Long Term Ecological Research Program, part of the US Long Term Ecological Research Network.

Visualizations

Here we will go through a series of visualization

Flipper and body mass in purple

Here, we plot flipper length against body mass

ggplot(data = penguins, aes(x = flipper_length_mm, y = body_mass_g))+
  geom_point(color = "purple")

## Warning: Removed 2 rows containing missing values (geom_point).

Flipper and body mass by species

Here, we plot filpper body length against body mass and look at the breakdown by species

ggplot(data = penguins, aes(x = flipper_length_mm, y = body_mass_g))+
  geom_point(aes(shape = species))

## Warning: Removed 2 rows containing missing values (geom_point).

Flipper and body mass by species and sex

Here, we plot flipper length against body mass and look at and look at the break down by species and sex

ggplot(data = penguins, aes(x = flipper_length_mm, y = body_mass_g))+
  geom_point(aes(color = species
                 , shape = species))+
  facet_wrap(~sex)
