Species have a variety of ways to exploit their environment when it comes to having offspring. As the species evolves, its reproductive strategy will drift towards either quantity or quality of offspring. This is called the r/K selection theory.

A guide to creating modern data visualizations with R. Starting with data preparation, topics include how to create effective univariate, bivariate, and multivariate graphs. In addition specialized graphs including geographic maps, the display of change over time, flow diagrams, interactive graphs, and graphs that help with the interpret statistical models are included. Focus is on the 45 most

However, exploratory analysis requires the use of certain graphs in R, which must be used for analyzing data. We shall now look into some of such important graphs in R. This part of the tutorial focuses on how to make graphs/charts with R. In this tutorial, you are going to use ggplot2 package. This package is built upon the consistent underlying of the book Grammar of graphics written by Wilkinson, 2005. ggplot2 is very flexible, incorporates many themes and plot specification at a high level of abstraction.

The r and K classification was originally proposed by the biologists Robert McArthur and E. O. Wilson (1967). The r selected species live in populations that are highly variable. The fittest individuals in these environments have many offspring and reproduce early.

The lowercase r is used to represent growth rate in ecological equations, and so is also used to represent species with a high reproductive rate. These species try to fill all available niches in an environment. Examples of r-selected species are many weeds such a dandelions, insects such as house flies and cockroaches, mice, passenger So basically you want the plotting area (area inside the x and y axis) to be the same for multiple graphs.
