First Plot demonstration

This is a demonstration showing how to make your first plot using R, Rstudio, and ggplot.

Steps:

• Be sure you are using the tidyverse and gapminder libraries (and that they are installed on your computer).
• Create a ggplot using the data gapminder and a mapping between data and aesthetic features. For example put GDP per capita on the x axis and life expectancy on the y axis.
• Make a scatterplot using geom_point

Refine your plot:

• Add axis labels using labs and the arguments x, y, title, subtitle, caption, tag (some of these are optional and not always needed.)
• Use theme to make the text bigger by setting the size property of text with the element_text function.
• Add colour to the plot. Change the label for your colour scale.
• Transform the x axis to be on a log scale using scale_x_log10

Repeat:

• Do this exercise with another dataset such as mtcars or palmerpenguins.
