Material status and resources:
The prose below refers to the very short methods and results sections that marks the beginning of our incredible dummy manuscript on Palmer penguins. Our research objective was to explore the relationship between flipper flipper length and body mass in the penguins inhabiting the Palmer archipelago (see figure below).
Sourced from the galapagos.org website.
Instead of using Word to write our manuscript, we are using RMarkdown to unify prose, code and figure-generation directly in a single document. We are also storing our document on Github, so we can perform version control and collaborate on it.
You can find the repository and the document here.
Our preliminary results are shown below. Any changes to be applied to this manuscript should be performed via pull requests.
Methods
Palmer Archipelago (Antarctica) penguin data
The data on three Palmer Archipelago (Antartica) penguin species - Adélie (Pygoscelis adeliae), Gentoo penguin (Pygoscelis papua) and Chinstrap penguin (Pygoscelis antarcticus) - used in our analyses were manually compiled from the original dataset made available by Dr. Kristen Gorman and the Palmer Station (Antarctica LTER, a member of the Long Term Ecological Research Network).
Statistical analyses
To explore the within-species relationship between penguin flipper length (mm) and body mass (g), we fit per-species simple linear models with flipper length (mm) as predictive variable, and body mass (g) as response variable.
Results
Our linear models show that body mass consistently increases with flipper length in all penguin species. [Something has gone terribly wrong! What should we do!].
Information on this dataset
This very simple exercise uses a subset of the
palmerpenguins R dataset. Original data comes
from Dr. Kristen Gorman and the Palmer Station, Antarctica LTER, a
member of the Long Term Ecological Research Network.
