mammalsmilkRA

The goal of mammalsmilkRA is to demonstate what the key parts of an analysis compendium for a paper or class project might look like and provide tutorials for how to carry out the relevant tasks.

Installation

Must have the devtools package. You can download if needed using install.packages("devtools").

Note that mammalsmilkRA requires a lot of other packages (has a lot of "dependencies" in R lingo) so you might be prompted to download or update other things, and it might take a little bit of time for R to work through all the download. Don't be alarmed by any red text.

devtools::install_github("brouwern/mammalsmilkRA")

library("mammalsmilkRA")

Example

Raw data as a .csv is included when the package is downloaded; for demonstration the data is also easily accessed as

data("milk")

The fat content of animals in the dataset ranges from new zero to almost 60%

hist(milk$fat)

An important point made in the paper is that contary to theoretical expectations, there is not a significant relationship between maternal size.

This relationship isn't significant even in a standard regression such as this one.

m <- lm(log10(fat) ~ log10(mass.fem), data = milk)

We can plot the relationship using basic graphics like this:

plot(log10(fat) ~ log10(mass.fem), data = milk)
abline(m, col =2)
